Abstract: Tires having white sidewalls are very popular in the United States and Canada. Tires having white lettering thereon are also very popular. This invention discloses a process for preparing such tires having decorative appliques thereon. By practicing the process of this invention, tires having better uniformity can be built at lower costs than when standard tire building techniques are utilized. This invention specifically relates to a method of preparing a pneumatic rubber tire having a decorative design on the sidewall thereof which comprises (a) applying the decorative applique to the sidewall of an uncured tire and (b) curing the tire; wherein the decorative applique is comprised of from about 25 weight percent to about 75 weight percent syndiotactic 1,2-polybutadiene having a melting point which is within the range of about 70.degree. C. to about 160.degree. C.

This invention specifically relates to a method of preparing a pneumatic rubber tire having a decorative applique on the sidewall thereof which comprises (a) applying the decorative applique to the sidewall of a cured tire and (b) binding the decorative applique to the sidewall by the application of heat and pressure; wherein the decorative applique is comprised of from about 25 weight percent to about 75 weight percent syndiotactic 1,2-polybutadiene or blends of SPBD having melting points which are within the range of about 70.degree. C. to about 160.degree. C.

Abstract: An ultra violet light polymerizable composition composed of a water dispersible liquid ethylenically unsaturated polyetherurethane of 0.5 to 5 parts of a photoinitiator and 0.01 to 0.5 parts of triaryl phosphine, the preferred photoinitiator being mono- or di-alkoxy benzoin having alkoxy radicals containing 1 to 20 carbon atoms.

Abstract: Thioperimidone has been discovered to be useful as an accelerator in the curing of chlorinated ethylenically unsaturated polymers such as polychloroprene with metal oxides such as magnesium oxide or zinc oxide.

Abstract: A liquid ethylenically unsaturated polurethane composition having no free NCO and a viscosity of 2,000 to 10,000 centipoises at 24.degree. C. dispersible in dilute caustic and capable of being polymerized by actinic light to yield a solid having a Shore A hardness of at least 30. Said composition may contain a diluent and a photosensitizing agent to adjust the viscosity and making the composition more readily utilizable for making printing plates.

Abstract: Laminates with staining rubber stocks can be made by adhering to the staining rubber stocks a nondiscoloring and nonstaining polyurethane comprising the reaction product of a mol of polyester of 1800 to 3500 molecular weight, 1.3 to 3.2 mols of a cycloaliphatic or an aliphatic diisocyanate and curing with 0.2 to 2.0 mols of an organic diamine or polyol of the nonstaining type, the polyester being polyhexanediol-ortho-phthalate or a blend of 50 to 80 percent of polyhexanediol-ortho-phthalate and 50 to 20 percent of polyhexanediol isophthalate.

Abstract: Cured polyurethane composition characterized by resistance to hydrolysis degradation prepared by reacting a polyurethane reaction mixture containing sufficient diamine curative in the presence of an excess of an epoxy resin.
