A NEW AND IMPROVED METHOD FOR THE PREPARATION OF CROSS-LINKED POLYCARBONATES, AND COMPOSITIONS MADE THEREFROM |
摘要 |
<p>An improved method for the preparation of cross-linked polycarbonates is disclosed, comprising the reaction at elevated temperature of a composition containing cyclic carbonate oligomers with at least one polyglycidyl acrylate copolymer formed by the reaction of at least one olefin with a glycidyl acrylate monomer. This invention also includes network polycarbonates wherein the carbonate chains are linked to each other via polyglycidyl acrylate copolymer groups. Further included within the scope of this invention are prepreg compositions which comprise a filler and a mixture of cyclic carbonate oligomers with a polyglycidyl acrylate copolymer.</p> |
