DIMETHACRYL OR DIACRYL OLIGOCARBONATES OBTAINED FROM DIANHYDROHEXITOL DIALKYLCARBONATE OR DIANHYDROHEXITOL CARBONATE DIMER, THEIR MANUFACTURING PROCESS AND THEIR USES

摘要

A process for the manufacture of a dimethacrylated or diacrylated oligocarbonate devoid of aromatic groups and phenolic functions comprising the stynthesis of a polyol oligocarbonate and a step consisting in reacting the polyol oligocarbonate 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.
