Abstract
A polymer composition may include a polymer produced from ethylene, and one or more vinyl carbonyl monomers having the general structure (I): where R, Rand Rare 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, (CRR), (CHR)—R, phenylene, CH—OR, and NR, wherein R, R, R, R, and Rare independently selected from a group consisting of hydrogen, halogen, CH, and alkyl, and wherein Ris independently selected from a group consisting of hydrogen; halogen; hydroxyl; alkyl; linear ether; cyclic ether; Si(R), wherein Ris independently selected from a group consisting of hydrogen, halogen, and alkyl; and (C═O)—R, wherein Ris an alkyl; and Ris independently selected from a group consisting of 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, where the polymer composition has a number average molecular weight (M) ranging from 5 kDa to 10000 kDa obtained by GPC.
