Claims9
A crosslinkable oligomer or polymer of the formula:
- where R, independently each occurrence, is an inert substituent, a monovalent crosslink forming group, X, or a polyvalent crosslink forming group, X′, with the proviso that in at least one repeat unit per molecule, at least one R is X or X′;
- x is a number from 1 to 10,000 and z is a number from 1 to 10,000 signifying the average number of repeat units in the composition;
- Z″ is a monovalent chain terminating group;
- and
- Z′ is independently each occurrence selected from the group consisting of monomers of the formula:
- where R1, independently each occurrence, is an inert substituent, X or X′, R5 is C1-10 alkyl, aryl or aralkyl;
- and n is 1 or 2.

- Z′ is independently each occurrence selected from the group consisting of monomers of the formula:
- and z is a number from 1 to 10,000 signifying the average number of repeating units in the composition,
- where R1, independently each occurrence, is an inert substituent, X or X′, R5 is C1-10 alkyl, aryl or aralkyl;
