Abstract

Branched poly(Bu acrylate) was obtained from pulsed-laser polymns. carried out in bulk and in soln. between -16 and +60 DegC. The predominantly short branches are formed by backbiting. The Arrhenius temp. dependence of the backbiting rate is calcd., and the activation energy of this process was found to be remarkably higher than that of propagation. Branching thus increases with temp. leading to broader SEC traces and difficulties in the accurate detn. of the rate of propagation. [on SciFinder (R)]
