Abstract
A polymer composition may include a polymer produced from ethylene, and one or more vinyl carbonyl monomers having the general structure (I): where R1, R2 and R3 are independently selected from a group consisting of hydrogen, halogen, hydroxyl, alkyl, substituted alkyl, alkoxy, substituted alkoxy, alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, aralkyl, (heterocyclo)alkyl, (heteroaryl)alkyl, (amino)alkyl, (alkylamino)alkyl, (dialkylamino)alkyl, carboxamino(alkyl), (cyano)alkyl, alkoxyalkyl, hydroxyalkyl, heteroalkyl, substituted cycloalkyl, substituted cycloalkoxy, substituted aryl, and substituted heterocycles; and Y and Z are independently selected from a group consisting of O, (CR5aR5b), (CHR6a)—R6b, phenylene, CH—OR7, and NR8, wherein R5a, R5b, R6a, R6b, and R8 are independently selected from a group consisting of hydrogen, halogen, CH2, and alkyl, and wherein R7 is independently selected from a group consisting of hydrogen; halogen; hydroxyl; alkyl; linear ether; cyclic ether; Si(R9)3, wherein R9 is independently selected from a group consisting of hydrogen, halogen, and alkyl; and (C═O)—R10, wherein R10 is an alkyl; and R4 is independently selected from a group co…
