Abstract
The present disclosure provides an ethylene-based polymer. The ethylene-based polymer is formed from reacting, under polymerization conditions, ethylene monomer and bisallyl maleate (“BAIIM”). The present ethylene-based polymer with ethylene monomer and bisallyl maleate branching agent is interchangeably referred to as “BAIIM-PE.”
Claims19
