  • LOW DENSITY POLYETHYLENE WITH ENHANCED ADHESION-TO-ALUMINUM FOIL BY BLENDING-IN ACID COPOLYMER RESINS
    Publication number: 20220267578
    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.

  • Ethylene-Based Polymer Composition with Branching
    Publication number: 20220259341
    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.
