PROCESS FOR PRODUCING SHORT-CHAIN MACROMOLECULES BASED ON ACRYLATE MONOMERS

摘要

Acrylate-based oligomers having double-bond end-group-functionalization are produced by means of free-radical polymerization where, in a first step, a monomer mixture of an acrylate component and of an aromatic component is reacted with use of a difunctional regulator, the quantity of the regulator being selected in such a way that the ratio of molar quantity of monomer mixture to that of regulator is from 100:20 to 100:0.5 and the polymerization is conducted until monomer conversion reaches at least 96%. In a second step, the resultant macromolecules are reacted, in the reactor in which the polymerization was conducted, with at least one compound Z which has a functional group and has an ethylenic double bond, and at least that portion of the compound Z that contains the ethylenic double bond becomes linked to the macromolecules via reaction of one of the functional groups of the difunctional regulator with the functional group of the compound Z.
