摘要
本文简单介绍了聚丙烯的化学改性的实施方法,讨论了适合聚丙烯接枝单体的种类和目前比较流行共单体选择方法,较详细地概括了聚丙烯化学改性后的表征方法,测定聚丙烯接枝率、接触角和表面自由能,并指出聚丙烯固体表面自由能可以更直接有效地反应出聚丙烯改性前后的极性。
The implementation of chemical modification for PP was introduced in this paper, and the type of appropriate grafting monomer for PP and the selection of currently popular co-monomer were discussed. In detailed, the characterization of PP after being modified was summarized, such as the measure of grafting ratio, contact angle and surface free energy. Especially, the rule that surface free energy of PP can directly and effectively reflect the polarity of PP before and after being modified was pointed out.
