POLYPERESTER-INITIATED GRAFT POLYMERIZATION
Abstract
Acrylate-styrene graft polymers were synthesized by initiating the polymerization of styrene with varying concentrations of partial tert-butylpolyperacrylic esters prepared from polymethylacrylate and polyacrylylchloride. Equations for calculating the molar compositions of the polyperesters were derived. The kinetics and degree of polymerization were established by polymer conversion data and viscosity-molecular weight determinations, respectively. The theoretical relationships between initiator concentration and rate of polymerization on the one hand, and between initiator concentration and degree of polymerization on the other, as predicted by the kinetics of free radical polymerization, were found to be valid in the present experimental system using a polymeric free radical source. A limited effort was also expended on an acrylatechloroprene graft polymer. (Author)
