Abstract: Disclosed herein is a recyclable barrier film comprising a first layer comprising high density polyethylene; and a barrier layer comprising a polymer other than polyethylene; where the polymer is operative to reduce the oxygen transmission rate through the barrier film relative to the oxygen transmission rate through the first layer; where the barrier layer is present in the barrier film in an amount of less than 5 weight percent, based on the total weight of the barrier film. Disclosed herein too is a method of manufacturing the disclosed barrier film.

Abstract: There is disclosed a method of carrying out an aqueous emulsion copolymerization to provide an alkali-soluble anionic copolymer having thickening characteristics while minimizing plating and grit problems in which the aqueous emulsion copolymerization of monoethylenically unsaturated monomers comprising from 15% to 50% by weight of carboxyl-functional monomer, at least about 10% by weight of monomer, preferably a urethane monomer, having surfactant characteristics, and the balance of the monomers being selected to provide a water insoluble copolymer, is carried out in the presence of a salt of an aromatic sulfonic acid, such as sodium styrene sulfonate, in an amount of from about 0.1% up to about 6.0%, by weight.
