PROCESS FOR MAKING A CATIONIC VINYL OLIGOMER COMPOSITION

摘要

A process is described for making an aqueous coating composition comprising a cationic vinyl oligomer comprising the following steps: I. preparation of a cationic vinyl oligomer by solution or bulk polymerisation of components: i) 2 to 50 wt% of vinyl monomers bearing amine functional groups selected from the group consisting of non-ionic amine functional groups (a), permanent quaternary ammonium functional groups (b), neutralised amine functional groups (c) and mixtures thereof; and ii) 20 to 98 wt% of Ci to Ci8 alkyl (meth)acrylates; and II. dispersion of the cationic vinyl oligomer in an aqueous medium and neutralisation of non-ionic amine functional groups.
