Patent number: 5433984Abstract: This invention provides an improved adhesive layer for multi-layer films and bottles, the adhesive layer being a graft copolymer of a polyolefin backbone with a methyl methacrylate graft. The graft copolymer sufficiently improves the compatibility between barrier resins and polyolefins to permit the production of monolithic or single layer bottles comprised of a blend of those three components. The resultant products have improved physical properties while retaining acceptable permeability to gases.Type: GrantFiled: October 13, 1993Date of Patent: July 18, 1995Assignee: Rohm and Haas CompanyInventors: Casmir S.

Patent number: 5229456Abstract: A novel graft copolymer capable of imparting to a polyolefin when blended therewith high tensile modulus and high sag resistance without increasing melt viscosity, and a method of making the same. The graft copolymer is a polyolefin having a relatively high weight-average molecular weight methacrylate polymer grafted thereto. The graft copolymer is formed by dissolving or swelling a non-polar polyolefin in an inert hydrocarbon solvent, heating to dissolve the polyolefin, and while stirring the mixture, adding a methacrylate monomer, together with an initiator to produce a constant, low concentration of radicals, to form a graft copolymer with a high molecular weight polymer chain covalently bonded or grafted to the polyolefin backbone. The graft copolymer can be separated from the solvent, isolated by volatilizing the solvent, for example in a devolatilizing extruder, and extruded into a desired shape such as a sheet, tube or the like. This graft copolymer can be blended with a poolyolefin matrix.Type: GrantFiled: January 31, 1992Date of Patent: July 20, 1993Assignee: Rohm and Haas CompanyInventors: Casmir S. Ilenda, Newman Bortnick, William J. Work

Patent number: 5202380Abstract: The addition of a polyolefin-acrylic graft copolymer to blends of polyolefin and core-shell polymers improves compatibility and allows core-shell polymers to be used as processing and performance modifiers polyolefins. Generally the compatibilizing additive is a graft copolymer of a polyolefin and a methacrylate. More specifically, the graft copolymer is derived from at least about 80% of a monomer of a methacrylic ester of the formula CH.sub.2 .dbd.C(CH.sub.3)COOR, where R may be alkyl, aryl, or aralkyl, substituted or unsubstituted, and less than 20%, based on a total monomer weight, of an acrylic or styrenic monomer copolymerizable with the methacrylic ester grafted on to a non polar polyolefin trunk, so that at least one chain is a polymer with a weight average molecular weight greater than about 20,000 and is present in a weight ratio with the polyolefin trunk of from about 1:9 to about 4:1.Type: GrantFiled: June 24, 1992Date of Patent: April 13, 1993Assignee: Rohm and Haas CompanyInventors: Casmir S.

Patent number: 4400500Abstract: This invention relates to polyaminoester thermosetting resins prepared by reacting polyalkylene maleate oligomers with polyfunctional amines via a Michael type addition reaction. The reaction is preferably conducted by a RIM process. Alpha, beta ethylenically unsaturated monomers, which are slow to react with amines, may be added to the reaction to copolymerize with the maleate functionality in a post cure step. The polyaminoester thermosetting resins are useful as plastics, coatings, resin modifiers, and elastomers.Type: GrantFiled: April 30, 1982Date of Patent: August 23, 1983Assignee: Rohm and Haas CompanyInventors: Everett J.
