The kinetics of the oxidation of tetralin inhibited by a number of phenols have been examined. The chain transfer reaction between phenoxy radicals and hydroperoxides is subject to both polar and steric effects. The rate of this reaction is increased by electron-attracting substituents on the phenol and is decreased both by ortho-alkyl groups on the phenol and by an increase in the size of the substituents on the hydroperoxides.

Chain Transfer Reaction

A random copolymer of isobutylene (IB) and 4-vinylbenzenecyclobutylene (4-VBCB) was synthesized by cationic polymerization at −80 °C using 2-chloro-2,4,4-trimethylpentane (TMPCl) as initiator. The laws of copolymerization were investigated by changing the feed quantities of 4-VBCB. The molecular weight of the copolymer decreased, and its molecular weight distribution (MWD) increased with increasing 4-VBCB content. We proposed a possible copolymerization mechanism behind the increase in the chain transfer reaction to 4-VBCB with increasing of feed quantities of 4-VBCB. The thermal properties of the copolymers were studied by solid-phase heating and crosslinking. After crosslinking, the decomposition and glass transition temperatures (Tg) of the copolymer increased, the network structure that formed did not break when reheated, and the mechanical properties remarkably improved.
