The properties of polymeric compositions can be improved by the presence of a polysiloxane unit of formula
where
Q is a substituted or unsubstituted aromatic group,
D is unsubstituted or substituted hydrocarbylene R1, R2, R3, R4, R5 and R6 each, independently, is unsubstituted or substituted hydrocarbyl.
x, y and z each independently has a value from 0 to 100.
Polyimides containing these units display improved solubility and adhesion; they are useful, among other things, as protective coatings.
聚合体组合物的性能可以通过存在式中的聚硅氧烷单元得到改善
式中
Q 是取代或未取代的芳香基团、
D为未取代或取代的烃基 R1、R2、R3、R4、R5 和 R6 各自独立地为未取代或取代的烃基。
x、y 和 z 各自独立地具有 0 至 100 之间的数值。
含有这些单元的聚酰亚胺具有更好的溶解性和粘附性,可用作保护涂层等。
