Abstract: The polymer blend includes at least 90% by weight low density polyethylene (LDPE) polymer and from 1% to 10% by weight acid copolymer based on the total weight of the polymer blend. In the polymer blend, the LDPE polymer has a melt index (I?2#191) from 2 g / 10 min to 8 g/10 min as determined in accordance with ASTM D1238, and a molecular weight distribution from 5 to 10.5. In the polymer blend, the acid copolymer is a polymerized reaction product of: at least 60% by weight ethylene, based on the total weight of the monomers present in the ethylene acid copolymer; from 1% to 20% by weight monocarboxylic acid monomer, based on the total weight of the monomers present in the ethylene acid copolymer; and from 0 to 20% by weight alkyl acrylate monomer, based on the total weight of the monomers present in the ethylene acid copolymer.

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."

Abstract: Irradiation of low-density polyethylene resins with an electron beam produces modified polyethylene resins that have significantly improved melt strength and retain useful melt-index and have few cross-linked gels, if the starting LDPE resin and the level of irradiation are properly selected.
