DEGRADABLE MATERIAL

摘要

A composition containing (a) an organic polymer, (b-l) one, two or more compounds of the formula (I) wherein m and n independently are an integer from 2 to 10 x 106; the recurring units X can have the same definition or different definitions, the recurring units Y can have the same definition or different definitions and the recurring units X and Y can have a random distribution or a block distribution; X is a group of the formula (ll-1-a) or (ll-1-b) and Y is a group of the formula (II-2); in which X1, X2, X3, X4 and X5 independently of one another are hydrogen, C1-C4alkyl or phenyl; A1 and A2 independently of one another are -O- 1/r Mr+, -O- N+(R1)4, -O-R2 or -N(R3)2, or A1 and A2 together form the radical -O- or the group -N-O-A0; A3 and A4 independently of one another are -O- 1/r Mr+, -O- N+(R1)4, -O-R2 Or -N(R3)2, or A3 and A4 together form the radical -O- or the group -N-O-A0; M is a metal cation of valency r with r being 1, 2, 3 or 4; R1, R2 and R3 independently of one another are hydrogen, C1-C20alkyl, C3-C12cycloalkyl unsubstituted or substituted by 1, 2 or 3 C1-C4alkyl; C5-C12cycloalkenyl unsubstituted or substituted by 1, 2 or 3 C1-C4alkyl; a bicyclic or tricyclic hydrocarbyl having 6 to 10 carbon atoms; phenyl unsubstituted or substituted by 1, 2 or 3 C1-C4alkyl; or C7-C9phenylalkyl unsubstituted or substituted on the phenyl by 1, 2 or 3 C1-C4alkyl; A0 is for example hydrogen; Y1, Y2, Y3 and Y4 independently of one another are hydrogen, C1-C4alkyl or phenyl; and (b-ll) optionally one, two or more inorganic or organic salts of a transition metal.
