ABSTRACT:
Vinyl addition polymer compositions, methods for forming such compositions, methods for using such compositions to form microelectronic and optoelectronic devices are provided. The vinyl addition polymer encompassed by such compositions has a polymer backbone having two or more distinct types of repeat units derived from norbornene-type monomers independently selected from monomers of Formula I:wherein each of X, m, R1, R2, R3, and R4is as defined herein and wherein a first type of repeat unit is derived from a glycidyl ether substituted norbornene monomer and a second type of repeat unit is derived from an aralkyl substituted norbornene monomer.
