A new and improved method for the preparation of cross-linked polycarbonates, and compositions made therefrom |
| abstract |
An improved method for the preparation of cross-nlinked polycarbonates is disclosed, comprising the reaction nat elevated temperature of a composition containing cyclic ncarbonate oligomers with at least one polyglycidyl acrylate ncopolymer formed by the reaction of at least one olefin with na glycidyl acrylate monomer. This invention also includes nnetwork polycarbonates wherein the carbonate chains are nlinked to each other via polyglycidyl acrylate copolymer ngroups. Further included within the scope of this invention nare prepreg compositions which comprise a filler and a nmixture of cyclic carbonate oligomers with a polyglycidyl nacrylate copolymer. |
