(EN) Copolyacetal
(ZH) 聚缩醛共聚物
Abrégé
(EN) A copolyacetal which is obtained by copolymerizing (A) 100 parts by weight of trioxane with (B) 0.01 to 10 parts by weight of at least one compound selected among glycidyl ether compounds represented by general formulae (I), (II), and (III) and (C) 0 to 20 parts by weight of a cyclic ether compound copolymerizable with trioxane (other than the compounds (B)). It is a polyacetal resin having high rigidity, excellent creep properties, a high surface hardness, and excellent sliding properties. In formula (I) (R<1> represents C1-12 alkyl, aryl, or substituted aryl). In formula (II) (R<2> represents a C2-20 poly(alkylene oxide) glycol residue). In formula (III) (R<4> represents C1-30 alkyl and R<5> represents C1-30 alkylene).
(ZH)

通过共聚合(A)100份(重量)三噁烷和(B)0.01-10份(重量)至少一种化合物(选自由通式(I)、(II)和(III)代表的缩水甘油醚化合物)以及(C)0-20份(重量)可与三噁烷共聚合的环醚化合物(不同于化合物(B))获得的共聚缩醛。这种聚缩醛树脂具有优异的刚度、优异的蠕变性能、高的表面硬度以及优异的滑动性能。在式(I)中R1代表C1-12烷基、芳基或取代的芳基。在式(II)中R2代表C2-20聚(烯化氧)二醇残基。在式(III)中R4代表C1-30烷基并且R5代表C1-30亚烷基。
