Abstract:
1. A process to prepare branched polymers comprising: performing a self-initiated free radical polymerization with a compound containing both a polymerisable double bond and a peroxide bond, which is used as an initiator and a branched monomer, vinyl monomer as a monomer, in which a molar ratio of the compound and the monomer is 1:2˜200, and a mass ratio of a solvent and the monomer is 0˜1.5:1, wherein the compound containing both the polymerisable double bond and the peroxide bond is peroxide (methyl)acrylate with a structural formula as follows: wherein R is —CH3 or and a polymerization reaction temperature is controlled at 60˜100° C., and a polymerization reaction time controlled is 8˜40 hours.
