OLIGOCARBONATES DIMETHACRYLES OR DIACRYLES OBTAINED FROM DIANHYDROHEXITOL DIALKYLCARBONATE OR DIANHYDROHEXITOL CARBONATE DIMER, PROCESS FOR THEIR MANUFACTURE AND USES THEREOF

摘要

A process for producing a dimethylcrystalline or diacrylated oligocarbonate of aromatic groups and phenolic functions, including oligolysis polyol stynthesis and a step of reacting the oligocarbonate polyol with a (meth) acrylant agent selected from methacryloyl chloride, methacrylic anhydride, methacrylic acid or acrylic acid, in order to obtain a dimethylcrystalline or diacrylated oligocarbonate ©.
