Abstract

Aseries of poly (1-octene-co-t-butyl ACRYLATE) were prepared by conventional free RADICAL POLYMERIZATION under mild conditions. The influence of different hightemperature decomposition initiators (e. g. , t-butyl peroxybenzoate, di-t-butyl peroxide) on copolymer composition was above all investigated. Subsequently, poly (1- octene-co-t-butyl ACRYLATE) was hydrolyzed to form amphiphilic poly (1-octene-co-acrylic acid). Thermal behaviours of poly (1-octene-co-t-butyl ACRYLATE) and poly (1-octene-coacrylic acid) and micellar behaviours of poly (1-octene-co-acrylic acid) in water were investigated. By using high-temperature initiators the copolymerization temperature can be increased which results in incremental incorporation of 1-octene and monomer conversion.1-Octene incorporation can be regulated in the range of 0~37.1 mol%. Meanwhile, molecular weights of these copolymers decreased as copolymerization temperature increased. The reactivity ratios of 1-octene (r1) and t-butyl ACRYLATE (r2) were figured out as r1=0.005±0.001 and r2=9.016±0.035. CMC Value of poly (1- octene-co-acrylic acid) in water increased as their molecular weight and 1-octene incorporation were lowered. However, the mean hydrodynamic radius decreased as molecular weight increased or 1-octene incorporation dropped. Although Tg value of poly (1-octene-co-acrylic acid) is much higher than that of poly (1-octene-co-t-butyl ACRYLATE), they all drop with the lowering of molecular weight or the increased 1-octene incorporation.
