This monomer is the adduct formed by reacting an aminoalkyl alkylene urea with about 0.9 up to about 1.5 molar proportions of a saturated monoepoxide to consume most or all of one of the two amino hydrogen atoms available, and then reacting with about 0.8 up to about 2.0 molar proportions of a monoisocyanate having a single acrylate or methacrylate group in the presence of at least 0.02%, based on the total weight of the reactants present, of an inhibitor which retards the free-radical polymerization of ethylenic unsaturation, such as hydroquinone, and phenothiazine.Type: GrantFiled: October 1, 1984Date of Patent: July 2, 1985Assignee: DeSoto, Inc.Inventors: Kazys Sekmakas, Raj Shah

Patent number: 4522735Abstract: Amines are reacted with phosphorous trichloride to form N-dichlorophosphinoamines that are then reacted with a bisphenol in about equimolar amounts to provide polyphosphoramidite oligomers. The polyphosphoramidite oligomers are effective as stabilizers for polymers such as polyolefins, and form even more efficient stabilizer combinations with hydroxyphenylalkyleneyl isocyanurates.Type: GrantFiled: June 17, 1983Date of Patent: June 11, 1985Assignee: The B. F. Goodrich CompanyInventor: Dwight W. Chasar

Patent number: 4511628Abstract: Rubber compositions and metal-reinforced rubber ply members have improved metal adhesion and metal adhesion retention. The improvement comprises admixing from about 0.5 to about 10.0 parts per hundred rubber (phr) of bis(2-mercaptobenzothiazato) nickel with a vulcanizable rubber composition prior to combining the metal and rubber and then curing. A method for improving the metal adhesion and metal adhesion retention between a vulcanizable rubber and metal member includes the step of dispersing from about 0.5 to about 10.0 phr of nickel in a vulcanizable rubber composition prior to curing.Type: GrantFiled: January 30, 1984Date of Patent: April 16, 1985Assignee: The Firestone Tire & Rubber CompanyInventors: Jung W. Kang, James A. Davis

Patent number: 4506046Abstract: A flame retardant non-opaque polycarbonate composition consisting essentially of, in admixture:(i) at least one halogen-free and sulfur containing aromatic polycarbonate resin derived from(a) at least one halogen-free and sulfur-free non-polycyclic dihydric phenol,(b) from about 4 to about 25 mole percent of at least one halogen-free thiodiphenol, based on the total amount of said halogen-free and sulfur-free non-polycyclic dihydric phenol and said halogen-free thiodiphenol employed, and(c) a carbonate precursor; and(ii) from about 0.001 to about 0.5 parts by weight per hundred parts by weight of said polycarbonate resin of at least one organic metal salt of sulfonic acid selected from the alkali and alkaline earth metal salts of sulfonic acids.Type: GrantFiled: April 4, 1984Date of Patent: March 19, 1985Assignee: General Electric CompanyInventor: Victor Mark
