1. A polymer adduct obtained by crosslinking a copolymer (P1) comprising:
recurring units (RP1) of formula (M):

OG Complex Work Unit Chemistry
recurring units (R*P1) of formula (N):

OG Complex Work Unit Chemistry
wherein
GN is selected from the group consisting of at least one of the following formulas:

OG Complex Work Unit Chemistry
each R1 is independently selected from the group consisting of a halogen, alkyl, alkenyl, alkynyl, aryl, ether, thioether, carboxylic acid, ester, amide, imide, alkali or alkaline earth metal sulfonate, alkyl sulfonate, alkali or alkaline earth metal phosphonate, alkyl phosphonate, amine and quaternary ammonium;
each i is independently selected from 0 to 4;
R2 is —(CH2)r-Si(OCH3)3, with r being selected from 1 to 5;
R3 is an alkyl group, an aryl group or an halogen group;
each k is independently selected from 0 to 4;
each j is independently selected from 3 to 7; and
T and Q are independently selected from the group consisting of a bond, —O—; —SO2—; —S—; —C(O)—; —C(CH3)2—; —C(CF3)2—; —C(═CCl2)—;
—C(CH3)(CH2CH2COOH)—; —N═N—; —RaC═CRb—, where each Ra and Rb, independently of one another, is a hydrogen or a C1-C12-alkyl, C1-C12-alkoxy, or C6-C18-aryl group; —(CH2)m— and —(CF2)m— with m being an integer from 1 to 6; an aliphatic divalent group, linear or branched, of up to 6 carbon atoms; and combinations thereof.
