Patent ID: 7754842

Claim:
A polymer comprising at least two cross-linkable polymers selected from the group consisting of the polymer of Formula I, the polymer of Formula II, and combinations thereof, wherein the at least two cross-linkable polymers are cross-linked via a chain-end crosslink, a Si—O—Si linkage, or both, and wherein Formula I is a polymer comprising the structure: wherein: R is a latent reactive group selected from the group consisting of hydrogen, alkoxy, phenoxy, and halogen, R′ is selected from the group consisting of alkyl, phenyl, hydrogen, halogen, alkoxy, and phenoxy, R 1 is a hydrocarbon chain having at least two CH 2 groups, coefficients z, x′ and y′ are integers greater than or equal to 1, coefficient y is an integer greater than or equal to 2, and C is a chain-end cross-linking molecule derived from a compound selected from: wherein: x is an integer greater than or equal to 2, R″ is any hydrocarbon, X is OMe, OR″ or NR″, and coefficient a is an integer ranging from 0 to 3; and Formula II is a polymer comprising the structure: wherein, coefficients x, y and z are integers greater than or equal to 1, and R″ is selected (CH 2 ) n CH═CH 2 and (CH 2 ) n CH═, wherein, (CH 2 ) n CH═ is a branching site whereby adjacent polymers are cross-linked and n is an integer greater than or equal to 2.
