Patent ID: 7557177

Claim:
A telechelic (co)polymer of the structure: Az-(M 1 ) x -X, wherein X is Cl, Br or a pseudohalogen group; M 1 is a monomer unit derived from a radically (co)polymerizable monomer unit having an average degree of polymerization x, and Az is a ring-opened azlactone group of the formula: wherein R 1 and R 2 are each independently selected from X, H, an alkyl group, a cycloalkyl group, a heterocyclic group, an arenyl group and an aryl group, or R 1 and R 2 taken together with the carbon to which they are attached form a carbocyclic ring; R 3 and R 4 are each independently selected from an alkyl group, a cycloalkyl group, an aryl group, an arenyl group, or R 3 and R 4 taken together with the carbon to which they are attached form a carbocyclic ring; R 5 is an organic or inorganic group, Q is a linking group selected from a covalent bond, (—CH 2 —) o , —CO—O—(CH 2 ) o —, —CO—O—(CH 2 CH 2 O) o —, —CO—NR 6 —(CH 2 ) o —, —CO—S—(CH 2 ) o —, where o is 1 to 12, Z is O, NH, S or NR 6 , wherein R 6 is H, an alkyl group, a cycloalkyl group, an arenyl group, a heterocyclic group or an aryl group; and n is 0 or 1.
