Abstract
The invention relates to a process for the preparation of compound(s) comprising at least one acrylate or methacrylate group, at least one linear carbonate group and at least one 5-membered cyclic carbonate group. The process comprises (A) a selective ring-opening step and (B) a (meth)acrylation step. The process is environment-friendly and compounds obtained are usable in radiation curable compositions, for example in radiation-curable inks.
