A polyether-polyamide block copolymer having an ethylenically unsaturated group is represented by formula (I):
and a polyether prepolymer thereof is represented by formula (II):
R¹ is H or an aliphatic hydrocarbon group, R² and R³ are each C2-6 aliphatic hydrocarbon, A is -OOC- or -OOC-NH-; B is C1-18 aliphatic hydrocarbon which may contain -NH-CO-NH, -NH-COO- or -NH-CO-; M is a hydrocarbon amide chain; Q is an ether or amino group, E is an aliphatic hydrocarbon ether or ester C1-12 group; V is an ethylenic hydrocarbon group; k=1-6, m=0-140, n=1-140, m+n=7-140; j, p, q=0 or 1, i=1-1000, r=5-500; and
Y is an isocyanate carbamoyl lactam, acid chloride or (oxy)carbonyl lactam group.
The prepolymer can be made by polymerizing an alcohol as R¹ component and an unsaturated 1,2- epoxy compound and/or a cyclic ether in the presence of an ionic catalyst to form a block or random copolymer; a component reactant then replaces the hydroxyl groups. The prepolymer is linked to a polyamide moiety by anionic polymerisation of a lactam; the block copolymer can be of A-B, A-B-A or multi-block type.
The drawings show NMR spectra of a prepolymer and copolymer.
The copolymer is moldable at high temperature and has good heat stability.
一种具有乙烯基不饱和基团的聚醚-聚酰胺嵌段共聚物由式(I)表示:
及其聚醚预聚物由式(II)表示:
R¹ 是 H 或脂肪族烃基,R² 和 R³ 分别是 C2-6 脂肪族烃,A 是 -OOC- 或 -OOC-NH-;B 是 C1-18 脂肪族烃,可含有 -NH-CO-NH、-NH-COO- 或 -NH-CO-;M 是烃酰胺链;Q 是醚基或氨基,E 是 C1-12 脂肪烃醚或酯基;V 是乙烯烃基;k=1-6,m=0-140,n=1-140,m+n=7-140;j、p、q=0 或 1,i=1-1000,r=5-500;以及
Y 是异氰酸酯氨基甲酰基内酰胺、酸氯化物或(氧)羰基内酰胺基团。
预聚物的制造方法是:在离子催化剂存在下,将作为 R¹ 组分的醇和不饱和 1,2-环氧化合物和/或环醚聚合,形成嵌段或无规共聚物;然后用一种组分反应物取代羟基。预聚物通过内酰胺的阴离子聚合与聚酰胺分子相连;嵌段共聚物可以是 A-B、A-B-A 或多嵌段类型。
图中显示了预聚物和共聚物的核磁共振光谱。
共聚物可在高温下成型,并具有良好的热稳定性。
