摘要
通过环氧化(苯乙烯-丁二烯-苯乙烯)三嵌段共聚物(SBS)与端羧基甲氧基聚乙二醇的开环反应,合成了带聚氧乙烯支链的两亲性SBS接枝物,通过红外光谱及核磁共振氢谱进行了表征,并确定了该两亲性聚合物具有良好的乳化性质及相转移催化性质.
Styrene-butadiene-styrene triblock copolymer（SBS） is a type of nonpolar thermoplastic elastomer, which can not be compatible or adherent to polar substance. Modification of SBS is necessary so as to widen its applications. Amphiphilic polymer is a kind of polymer containing both hydrophilic and hydrophobic groups or segments[1]. Amphiphilic SBS copolymer containing hydrophilic segments can be obtained by copolymerization of SBS with hydrophilic monomers,
