    • The present invention discloses non-hydrolyzable, block, (AB).sub.n A type, copolymers comprising alternating units of polysiloxane and amino-polyalkyleneoxide and provides a method for the preparation of these copolymers. Also provided is the use of these copolymers as softeners, in particular durable, hydrophilic textile softeners, which improve tactile properties of the textiles substrates treated with the commercial soil release finishes, without substantially detracting from their properties. The copolymers of the present invention have alternating units of polysiloxane [X(C.sub.a H.sub.2a O).sub.b R.sup.2 [(SiO(R.sup.1).sub.2 ].sub.c Si(R.sup.1).sub.2 R.sup.2 (C.sub.a H.sub.2a O).sub.b X] and polyalkyleneoxides [YO(C.sub.a H.sub.2a O).sub.d Y] wherein R.sup.1 is a C.sub.1 to C.sub.4 alkyl, preferably methyl, R.sup.2 is a divalent organic moiety, X and Y are divalent organic groups selected from a secondary or tertiary amine and a ring opened epoxide, such that when X is a ring opened epoxide, Y is an amine and vice versa, a=2 to 4, preferably 2 to 3, b=0 to 100, d=0 to 100, b+d=1 to 100, preferably 10 to 50, and c=1 to 500, preferably 10 to 100.
    • 本发明公开了不可水解的嵌段(AB)nA型共聚物,其包含聚硅氧烷和氨基 - 聚亚烷基氧的​​交替单元,并提供了制备这些共聚物的方法。 还提供了这些共聚物作为软化剂的用途,特别是耐久的亲水织物柔软剂,其改善了用商业污垢释放整理剂处理的纺织品基材的触觉性能,而基本上不损害其性能。 本发明的共聚物具有聚硅氧烷[X(CaH2aO)bR2 [(SiO(R1)2] cSi(R1)2R2(CaH2aO)bX]和聚环氧烷烃[YO(CaH2aO)dY])的交替单元,其中R1为C1〜 C4烷基,优选甲基,R2是二价有机部分,X和Y是选自仲胺或叔胺和开环环氧化物的二价有机基团,使得当X是开环的环氧化物时,Y是胺,反之亦然 a = 2〜4,优选2〜3,b = 0〜100,d = 0〜100,b + d = 1〜100,优选为10〜50,c = 1〜500,优选为10〜100。
