Abstract:
Functionalized and polymerizable polymer, which contains the following repeat units (IA), (IB) and (IC): where X, Aâ€”B, Y, P, Z, U, V, T, R1, R2, R3, R4 and R5 independently of one another have the following meanings: X=CH2 or O; Aâ€”B=Câ€”C or C&boxH;C; Y=CH2O, COâ€”O or COOâ€”R1â€”O, where R1=substituted or unsubstituted C1 to C5 alkylene or oxyalkylene; P=a polymerizable group CH2&boxH;C(CH3)â€”COâ€”; Z=H, COOH, substituted or unsubstituted C1 to C12 alkyl or COOR4, where R4=substituted or unsubstituted C1 to C12 alkyl or C6 to C14 aryl; U=COOH or COOR5, where R5=substituted or unsubstituted C1 to C12 alkyl or C6 to C14 aryl; V=H, COOH, CH2â€”OH, OR2 or COâ€”OR2, where R2=substituted or unsubstituted C1 to C12 alkyl or C6 to C14 aryl; and T=O, NH or NHR3, where R3=substituted or unsubstituted C1 to C12 alkyl or C6 to C14 aryl; and where the mole fraction a of the unit (IA), the mole fraction b of the unit (IB) and the mole fraction c of the unit (IC) are as follows: a=0.05 to 1.0; b=0 to 0.95; and c=0 to 0.90.
