Patent ID: 7442756

Claim:
A polymer compound having a polymer main chain and functional groups A and B, in which the functional group A can be bonded to silicon-containing materials and/or metal nitrides and has the following structure: (R 2 —O—) 3-n SiR 1 n —R 3 , wherein n=1 or 2, R 1 and R 2 are in each case an alkyl or aryl group, it being possible for R 1 and R 2 to be identical or different, and R 3 is an alkylene or arylene group; and the functional group B can be bonded to copper metal and/or tantalum, metal oxides, copper(I) oxide and/or copper(Il) oxide and has one or more of the following structures: wherein R 1 and R 3 are as defined in group A, and groups A and B are each linked to the polymer main chain via R 3 .
