DIMETHACRYLATED OR DIACRYLATED OLIGOCARBONATES OBTAINED FROM DIANHYDROHEXITOL DIALKYLCARBONATE OR A DIMER OF DIANHYDROHEXITOL CARBONATE, PROCESS FOR PRODUCING SAME AND USES THEREOF

摘要

A process for producing a dimethacrylated or diacrylated oligocarbonate devoid of aromatic groups and phenolic functions, comprising the synthesis of an oligocarbonate polyol and a step consisting in reacting the oligocarbonate polyol with a (meth)acrylating agent chosen from methacryloyl chloride, methacrylic anhydride, methacrylic acid or acrylic acid, in order to obtain a dimethacrylated or diacrylated oligocarbonate.
