摘要

1引言由于SBS化学组成及其结构的待点

将它作为粘合剂

比一般合成橡胶粘合剂更具独特之处.然而由于SBS大分子内缺少极性基团

使得SBS粘合剂与聚氯乙烯、聚氨酯和金属等材料的粘接效果不够理想

为改善其粘接性

国内外学者对其进行了接枝改性的研究.

Abstract

Due to its chemical composition and structure SBS has unique adhesive function. However

in the absence of polar group in SBS macromolecules

its adhesion to metal is weak. In this paper

SBS was melted and reacted with maleic anhydride (MAH)

methyl methacrylate (MMA) and the mixture of MAH and MMA to improve its adhesion to metal

The results show that the strength of adhesion to alumimium of SBS adhesives modified by melting reaction with the mixture of MAH and MMA is stronger than those of SBS modified by MAH or MMA separately. Besides

the melting reaction had an notable effect on the formation of microphase segregation structure of SBS.
