A Simple and Facile Approach to Aliphatic N-Substituted Functional Eight-Membered Cyclic Carbonates and Their Organocatalytic Polymerization

Aliphatic N-substituted functional eight-membered cyclic carbonates were synthesized from N-substituted diethanolamines by intramolecular cyclization. On the basis of the N-substituent, three major subclasses of carbonate monomers were synthesized (N-aryl, N-alkyl and N-carbamate). Organocatalytic ring opening polymerization (ROP) of eight-membered cyclic carbonates was explored as a route to access narrowly dispersed polymers of predictable molecular weights. Polymerization kinetics was highly dependent on the substituent on the nitrogen atom and the catalyst used for the reaction. The use of triazabicyclodecene (TBD), instead of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), as the catalyst for the N-alkyl substituted monomers significantly enhanced the rate of polymerizations. Computational studies were performed to rationalize the observed trends for TBD catalyzed polymerizations. With the optimal organocatalyst all monomers could be polymerized generating well-defined polymers within a timespan of ?2 h with relatively high monomer conversion (?80%) and low molar-mass dispersity (D sign;M ? 1.3). Both the glass transition temperatures (Tg) and onset of degradation temperatures (Tonset) of these polymers were found to be N-substituent dependent and were in the range of about’45 to 35 C and 230 to 333 C, respectively. The copolymerization of the eight membered monomers with 6-membered cyclic comonomers including commercially available l-lactide and trimethylene carbonate produced novel copolymers. The combination of inexpensive starting materials, ease of ring-closure and subsequent polymerization makes this an attractive route to functional polycarbontes.

DENTAL COMPOSITIONS BASED ON NANOFIBER REINFORCEMENT

A dental material using nano material that will serve as reinforcement and will enhance mechanical properties with minimal sacrifice in other properties including processability of a dental material. The dental material may be used as a filling, restorative, cement, liner, adhesive or primer. This is achieved by combining several polymerizable monomers and/or oligomers, a polymerization initiator, at least one hyperbranched additive and at least one of an electrospun nanofiber, an electrospun nanosphere or a hyperbranched macromolecule. The hyperbranched additive may be hyperbranched molecules, dendridic molecules (such as dendrimers). In a preferred embodiment a caged silica (such as POSS) is used for a caged macromolecule. The material may also include nanoclay or traditional composite fillers. The material may optionally include accelerators (such as DEHPT), cross linkers or pigment

Curable composition

A curable composition comprising: (A) 100 parts by mass of a monomer component which comprises a radically polymerizable monomer and has a water absorbing capacity of not larger than 20% by weight; (B) 0.5 to 10 parts by mass of water; (C) 0.1 to 20 parts by mass of a surfactant; and (D) an effective amount of a radical polymerization initiator. The curable composition is cured by polymerization in a state where a water layer is formed on the surfaces of the cured body that is being formed, effectively suppressing the hindrance of polymerization caused by oxygen and decreasing the formation of unpolymerized product on the surfaces of the cured body. The curable composition is particularly useful as a dental restorative.

ANAEROBIC COMPOSITE MATRIX RESINS

A matrix resin composition for fiber reinforced composite materials is described. The resin is thermosetting and achieves a glass transition temperature of at least 177 C. (Tg), obtained by curing under anaerobic conditions at room temperature. The matrix resin will streamline composite fabrication processes by eliminating the need for heating during the cure process. The implications of this development are significant in terms of the ease of use and elimination of procedural steps. While the resin system was developed specifically for vacuum bagging, it is expected to be viable for other composite fabrication methods including resin transfer molding (RTM) and vacuum-assisted resin transfer molding (VARTM). The resin system is viable for use with carbon fiber reinforcements to fabricate laminates at least 0.20 inches thick. The resulting laminintes have low porosity and mechanical properties equivalent to those prepared with common epoxy matrix resins.

A compilation of two decades of mutagenicity test results with the ames Salmonella typhimurium and L5178Y mouse lymphoma cell mutation assays

As previously reported [Cameron, T. P., Rogers-Back, A. M., Lawlor, T. E., Harbell, J. W., Seifried, H. E., and Dunkel, V. C. (1991) Gentoxicity of multifunctional acrylates in the Salmonella/mammalian-microsome assay and mouse lymphoma TK+/- assay. Environ. Mol. Mutagen. 17, 264-271], the National Cancer Institute (NCI) shares the responsibility of selecting the most significant chemicals for carcinogenicity testing by the National Toxicology Program (NTP) and has used data from Salmonella and mouse lymphoma mutagenicity assays to aid in the selection and prioritization of chemicals to be further evaluated in chronic 2 year rodent studies. In addition, a number of antineoplastic and anti-AIDS drugs in preclinical evaluation were tested for the NCI’s Division of Cancer Treatment Toxicology Branch. In the NCI/NTP chemical selection process, it is no longer necessary to test chemicals prior to sending them to the NTP so the NCI program has ceased performing mutagenicity tests. Some of the testing data has been made available in summary form in the Chemical Carcinogenisis Research Information System (CCRIS), which is searchable on the NLM TOXNET system. The limitations in using this source are that only summary results are available and many negative test results are not included. A summary table that presents the results for each compound is provided in the Appendix with raw data provided in the Supporting Information. The Appendix table contains the compound name, CAS number, and a summary of the data from the Ames test and the mouse lymphoma assay.
