Patent number: 5057366Abstract: The invention provides normally tacky and pressure-sensitive adhesive compositions comprising a polymer having an inherent viscosity greater than 0.2 and having in its backbone at least a major portion by weight of polymerized monomeric acrylic or methacrylic acid ester of a non-tertiary alcohol and, having attached to the backbone, polymeric moieties having a weight average molecular weight of above about 2,000 and a T.sub.g of above about 20.degree. C. The number and composition of the attached moieties in the polymer is such as to provide the adhesive composition with a shear holding value of at least 50 minutes. Sheet materials coated with the adhesive composition are also provided. Preferred adhesive composition comprises a copolymer monomeric acrylic or methacrylic acid ester of non-tertiary alcohol and macromolecular monomer. The copolymer may also include up to 12% by weight of a copolymerizable polar monomer such as acrylic acid.Type: GrantFiled: September 16, 1982Date of Patent: October 15, 1991Assignee: Minnesota Mining and Manufacturing CompanyInventors: James R. Husman, James N. Kellen, Rebecca E. McCluney, Michael L. Tumey

Patent number: 4975320Abstract: A two stage polymerization process for preparing a vinyl acetate/ethylene emulsion copolymer containing a monomer which is normally incompatible with vinyl acetate. In the first stage the vinyl acetate and ethylene and, optionally, an active crosslinking comonomer and/or latent crosslinking comonomer are free radical polymerized in the presence of a stabilizing system to yield a first stage polymer emulsion. When the free vinyl acetate monomer content of the first stage emulsion is less than about 5%, the second stage polymerization begins by adding the incompatible monomer. Preferably, there is no cessation of the addition of the free radical source during the transition from the first stage to the second stage polymerization. No additional stabilizing system is added to the reaction in the second stage.Vinyl acetate/ethylene/incompatible comonomer/latent crosslinking comonomer copolymers prepared by the two stage polymerization process are suitably used as binders for making nonwoven products.Type: GrantFiled: February 1, 1989Date of Patent: December 4, 1990Assignee: Air Products and Chemicals, Inc.Inventors: Joel E. Goldstein, Chung-Ling Mao, John G. Iacoviello

Patent number: 4968558Abstract: A pressure sensitive adhesive is prepared by the polymerization of an appropriate acrylic ester formulation of the type that includes an ethylenically unsaturated monomer having a polar group, and at least part of such polymerization is accomplished by photopolymerization using a source of ultraviolet radiation that provides a substantial portion of its ultraviolet radiation in the wavelength band of from about 280 to about 350 nm and a light intensity at the surface of the formuation being polymerized of no more than about 4.0 milliwatts/cm.sup.2.Type: GrantFiled: November 2, 1989Date of Patent: November 6, 1990Assignee: Nalco Chemical CompanyInventors: Dennis K. Fisher, Brian J. Briddell

Patent number: 4942086Abstract: Heat resistance binders for flexible polyester webs may be prepared using an emulsion polymer,the polymer being prepared by a two-stage polymerization procedure wherein a first stage is prepared based on a relatively low Tg ethylene vinyl acetate polymer and a second stage higher Tg polymer thereby combining the advantageous flexibility and film forming properties of the ethylene vinyl acetate copolymer with the stiffness and heat resistance of the higher Tg copolymer.Type: GrantFiled: September 9, 1988Date of Patent: July 17, 1990Assignee: National Starch and Chemical Investment Holding CorporationInventors: Paul R. Mudge, James J. Walker, Ronald Pangrazi
