  • Patent number: 5455307
    Abstract: The present invention provides for polymeric stabilizers which are the acid-catalyzed reaction product of a phenolic compound or a ring substituted aromatic compound and an olefin polymer containing either terminal unsaturation and/or pendant unsaturation along the polymer chain. These stabilizers are readily compatiable with olefin polymer and copolymer matrixes and offer good protection of the matrix polymer against one or more of heat, oxygen, ultra violet or radiation degradation. Other advantages include low volatilization as well as low tendency to migrate from the polymer matrix.

  • Patent number: 5262484
    Abstract: Graft copolymers and processes for the preparation thereof are provided. The copolymers comprise a base polymer having grafted thereto a monomeric 2-alkenyl azlactone. The surface properties of the graft copolymers can be modified by binding thereto nucleophilic reagents comprising further functional groups with desired properties. Further, the amount of azlactone available at the surface of a graft copolymer for binding to such nucleophilic reagents can be controlled by selecting a surface against which the graft copolymer is formed. The graft copolymers exhibit desirable thermoplastic, melt flow, and adhesion properties and are particularly useful for immobilizing proteins. Methods of immunoassay based on the immobilization of proteins are also disclosed. Another utility of the graft copolymers involves the compatibilizing of immiscible polymer blends.

  • Patent number: 5254636
    Abstract: This invention relates to a process which significantly reduces the time for hydrolyzing a crosslinked maleic anhydride/lower alkyl vinyl ether copolymer to a clear gel which comprises suspending or dispersing fine granules of the crosslinked copolymer in deionized water and agitating the resulting dispersion or suspension for a period of between about 15 and about 130 minutes at a temperature of from about 60.degree. to about 90.degree. C. and then cooling the hydrolyzed mixture before introducing a basic neutralizing agent at a temperature of from about 15.degree. to about 85.degree. C. to produce a clear, homogeneous hydrolyzed gel having a Brookfield viscosity of from 5,000 to 250,000 cps.

  • Patent number: 5248717
    Abstract: This invention relates to novel hydroxy-functional polyester diluents, and more particularly, to acrylic-modified hydroxy-functional polyester reactive diluents useful for blending with a variety of thermosetting or thermoplastic film-forming polymers. More specifically, the hydroxy-functional polyester reactive diluents are essentially low molecular weight polyesters derived from triols, and a combination of unsaturated monocarboxylic acids and saturated monocarboxylic acids. These hydroxy-functional polyester diluents may be copolymerized with one or more acrylic monomers, i.e. hydroxy-functional acrylic monomers, and blended with a variety of thermosetting or thermoplastic film-forming polymers. These blends of the film-forming polymers and the hydroxy-functional polyester diluents can be crosslinked with conventional crosslinking agents such as isocyanates and used in the formulation of low VOC paint compositions particularly useful as automotive topcoats.

  • Patent number: 5239017
    Abstract: A continuous process for the production of pressure sensitive adhesive mass compositions and adhesive elements which exhibit excellent properties with respect to a variety of substrates, which is non-toxic and non-sensitizing. The element exhibits high cohesive strength so that its integrity is maintained on removal from the substrate leaving no residues and is highly flexible so that total confirmation with the underlying shape of the substrate is maintained. The adhesive composition includes the hydrolysis/esterification product of a methyl vinyl ether/maleic anhydride copolymer with an hydroxylated compound. In this invention, the adhesive element is prepared by microwave heating of a mixture of the copolymer and hydroxylated compound, preferably with a surfactant, in the presence of water.

  • Patent number: 5229466
    Abstract: The present invention relates to a powdery absorbing material for aqueous liquids based on a water-swellable powdery polymer having at least 0.2 equivalents carboxyl groups per 100 parts by weight which are neutralized by 50 to 99, advantageously by at least 80 mole %. The powdery absorbing material is obtained by treating the water-swellable carboxyl-groups-containing polymer with a solution of an N-(hydroxyalkyl).beta.-(meth)-alanine ester or with the polycondensation products thereof. As a solvent for the powdery absorbing material, water is used which either contains water-miscible organic diluents which evaporate on heating, or non-evaporative water-miscible organic diluents, i.e., diluents remaining in the polymer.
