CA 2220104

The present invention discloses non-hydrolyzable, block, (AB)nA 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(CaH2aO)bR2[(SiO(R1)2]cSi(R1)2R2(CaH2aO)bX] and polyalkyleneoxides [YO(CaH2aO)dY] wherein R1 is a C1 to C4 alkyl, preferably methyl, R2 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.

L'invention porte sur des copolymères blocs non hydrolysables de type (AB)¿n?A comprenant des unités alternées de polysiloxane et d'aminopolyalkylèneoxyde, et sur leur procédé de préparation. Elle porte également sur leur utilisation comme adoucisseurs et en particulier comme adoucisseurs hydrophiles pour textiles améliorant le toucher des substrats textiles traités avec les apprêts antisalissures du commerce, sans généralement nuire à leurs propriétés. Les copolymères de l'invention présentent des unités alternées de polysiloxane de la formule [X(C¿a?H¿2a?O)¿b?R?2¿[(SiO(R?1¿)¿2?]¿c?Si(R?1¿)¿2?R?2¿(C¿a?H¿2a?O)¿b?X] et de polyalkylèneoxydes de la formule [YO(C¿a?H¿2a?O)¿d?Y] dans lesquelles R?1¿ est alkyle C¿1?-C¿4? ou de préférence méthyle, R?2¿ est un fragment organique divalent, X et Y sont des groupes organiques divalents choisis entre une amine secondaire ou tertiaire et un époxyde à cycle ouvert, de telle sorte que, lorsque X est un époxyde à cycle ouvert, Y est une amine, et vice versa, a = 2 à 4, et de préférence 2 - 3, b = 0 à 100, d = 0 à 100, b + d = 1 à 100 et de préférence de 10 à 50, et c = 1 à 500, et de préférence de 10 à 100.
