Abstract

Group transfer polymerization (GTP) of methyl methacrylate (MMA) was carried out using potassium bibenzoate (KBB) in presence of 18-crown-6 as catalyst and 1-methoxy-1-(trimethylsiloxy)-2-methyl-1-propene (MTS) as initiator in tetrahydrofuran (THF) at 25°C. The performance of this catalyst was compared with tetrabutylammonium bibenzoate (TBABB) catalyst. Broader polydispersity and lower initiator efficiency were observed for the polymers prepared using KBB/18-C-6 catalyst. Kinetic studies were conducted using both catalysts under identical conditions to better understand the effect of the countercation in GTP.
