These materials contain a backbone segment, such as polyacrylate, having pendant therefrom mono- or disubstituted olefinic groups, such as vinyl itaconate, having specific polymerization rates. This class of materials, especially when coupled with specifically-defined oxygen-activated catalyst systems, provide paint and plastic compositions which exhibit excellent film formation, strength and durability characteristics.Type: GrantFiled: October 31, 1983Date of Patent: March 19, 1985Assignee: The Procter & Gamble CompanyInventors: Rodney D. Bush, Medford D. Robbins

Patent number: 4500683Abstract: A pressure-sensitive adhesive composition containing as a polymer component an addition-polymerization polymer of an acryl-based polymer having sticking properties at room temperature and one or more ethylenically unsaturated monomers capable of forming a homo- or co-polymer having a glass transition point of at least 273.degree. K.; the addition-polymerization polymer is prepared by polymerizing one or more ethylenically unsaturated monomers in the presence of the acryl-based polymer; the present pressure-sensitive adhesive composition has high adhesive strength and cohesive strength.Type: GrantFiled: June 8, 1984Date of Patent: February 19, 1985Assignee: Nitto Electric Industrial Co., Ltd.Inventors: Yutaka Hori, Makoto Sunakawa, Kikuo Takayama, Naoki Matsuoka, Yutaka Moroishi

Patent number: 4500466Abstract: Vulcanizable polymeric compositions comprising certain rubbery polymers or polymer blends, a zinc dimethacrylate adjuvant having a surface area of from about 3.7 to about 5.4 m.sup.2 /g or more and a peroxide curing agent are provided. Polymeric compositions which contain 25 parts by weight or more of the zinc dimethacrylate adjuvant per 100 parts by weight of rubbery polymer in the absence of reinforcing fillers exhibit excellent strength and hysteresis characteristics when cured. The surface area of the zinc dimethacrylate adjuvant along with its method of preparation are extremely important factors in the excellent properties obtained when polymeric compositions containing the adjuvant are cured.Type: GrantFiled: October 20, 1983Date of Patent: February 19, 1985Assignee: The Firestone Tire & Rubber CompanyInventors: Robert A. Hayes, Wendell R. Conard

Patent number: 4495326Abstract: Sulfur-curable, carbon black reinforced material rubber compounds having improved processing properties in the uncured state and improved strength and dynamic properties in the cured state are obtained by the addition of from about 0.2 to about 15 parts by weight per 100 parts by weight of natural rubber of a zinc dimethacrylate having a surface area of from about 3.7 to about 5.4 m.sup.2 /g or more to the compounds. The addition of the zinc dimethacrylate to the compounds permits the use of lower quantities of carbon black than would ordinarily be employed in the absence of the zinc dimethacrylate while still providing for the improved properties.Type: GrantFiled: January 9, 1984Date of Patent: January 22, 1985Assignee: The Firestone Tire & Rubber CompanyInventors: Thomas F. Donatelli, Philip F. Murray

Patent number: RE32889Abstract: Cyanoacrylate compositions which employ fumed silicas treated with polydimethylsiloxane or trialkoxyalkylsilane are stable and exhibit an unexpectedly high thixotropic ratio. Such compositions are useful in adhesive applications or, when stabilized so as to prevent polymerizaton in contact with moisture, in latent fingerprint developing applications.Type: GrantFiled: October 14, 1986Date of Patent: March 14, 1989Assignee: Loctite CorporationInventor: Alan E. Litke
