Patent number: 4503184Abstract: Aqueous dispersions containing a mixture of 20 to 80% by weight of a latex of a copolymer A of butadiene, styrene and at least one unsaturated carboxylic acid, and 80 to 20% by weight of latex of a copolymer B of styrene, an alkyl acrylate and, if appropriate, at least one unsaturated carboxylic acid. The dispersions can be used as binders for the preparation of adhesive compositions suitable for joining or gluing two or more elements, and particularly suitable when at least one of the elements consists of a material which is difficult to glue, such as polyvinyl chloride.Type: GrantFiled: July 7, 1983Date of Patent: March 5, 1985Assignee: Rhone-Poulenc Specialities ChimiquesInventor: Jacques Marongiu
-
Patent number: 4497941Abstract: Ethylene-vinyl acetate copolymers having a melt index of 700 to 10000 and containing from 11 to 40% vinyl acetate are useful in hot melt systems and particularly in formulating low viscosity hot melt adhesives, preferably in binary compositions with natural or synthetic resin tackifiers. The adhesives show long open times with short setting times, and excellent adhesive properties.The EVAs are prepared by a high pressure polymerization, preferably by using chain transfer agent such as isobutylene to achieve high melt indices.Type: GrantFiled: September 30, 1982Date of Patent: February 5, 1985Assignee: Exxon Research & Engineering Co.Inventors: Giorgio Aliani, Jacques B. Lechat, Jozef A. F. Smits

Patent number: 4497931Abstract: Antioxidants are enhanced in their activity by the presence of soluble lithium ion.Type: GrantFiled: July 1, 1983Date of Patent: February 5, 1985Assignee: Union Camp CorporationInventor: Samuel D. Hollis
-
Patent number: 4491655Abstract: There is disclosed the use of esters especially methyl esters of rosin acids as total or partial replacements for oil in rubber formulations. Vulcanizate properties, low temperature performance, and processibility are comparable when using either the rosin ester or an aromatic oil, however, the rosin ester extended rubber demonstrates improved abrasion resistance and flex resistance.Type: GrantFiled: January 6, 1984Date of Patent: January 1, 1985Assignee: The Goodyear Tire & Rubber CompanyInventor: Paul H. Sandstrom
-
Patent number: 4478993Abstract: There is disclosed the use of decarboxylated rosins as total or partial replacements for oil in rubber formulations. Vulcanizate properties, low temperature performance, and processibility are comparable when using either the decarboxylated rosins or an aromatic extending oil, however, the decarboxylated rosin extended rubber demonstrates improved abrasion resistance.Type: GrantFiled: January 6, 1984Date of Patent: October 23, 1984Assignee: The Goodyear Tire & Rubber CompanyInventors: Lawson G. Wideman, Paul H. Sandstrom
-
Patent number: 4477613Abstract: There is provided a stabilized aqueous base tackifier composition characterized by the presence in an aqueous medium of a resinous tackifier composition having an acid number in the range from 30 to 150 and a softening point in the range of from -40.degree. to 150.degree. C., a minor amount of a nonionic or anionic surfactant and a minor amount of an elastomeric latex. There is also provided a method of stabilizing an emulsifiable tackifier composition which comprises adding to such composition, a minor amount of a surfactant and a minor amount of an elastomer.Type: GrantFiled: August 1, 1983Date of Patent: October 16, 1984Assignee: Sylvachem CorporationInventors: James M. Evans, Kenneth E. Krajca, Keijo A. Ukkonen, James E. Hansen

Patent number: 4463115Abstract: A pressure sensitive adhesive composition comprising (A) a polyether having at least one silicon-containing hydrolyzable group, having an average molecular weight of 300 to 30,000 and having a principal chain which is essentially constructed with the chemically bonded recurring units:--R.sup.1 --O--wherein R.sup.1 is a divalent alkylene group and (B) a tackifier; said tackifier being admixed with the polyether in an amount of 10 to 140 parts by weight per 100 parts by weight of said polyether. From the composition a pressure sensitive adhesive product having good adhesive properties can be prepared substantially without a solvent.Type: GrantFiled: October 7, 1983Date of Patent: July 31, 1984Assignee: Kanegafuchi Kagaku Kogyo Kabushiki KaishaInventors: Toshifumi Hirose, Katsuhiko Isayama
