  • Patent number: 5832636
    Abstract: The present invention provides an article of footwear having an upper and a non-clogging sole attached to the upper. The sole includes a generally planar ground engaging surface and at least one traction member or cleat projecting from the generally planar ground engaging surface. The traction member or cleat is attached with a base surface adjacent the generally planar ground engaging surface, side surfaces projecting downwards, and a tip attached at a bottom end of the traction member. At least a portion of the base surface and the side surfaces of the traction member or cleat and at least a portion of the ground engaging surface of the sole includes an adhesion prevention material having both a low coefficient of friction and a low wettability with respect to water in a preferred embodiment. However, the tip of the traction member remains substantially free of the adhesion prevention material. The adhesion prevention material has a coefficient of friction of less than 0.4, preferably between 0.1 and 0.

  • Patent number: 4184997
    Abstract: Fiber-reinforced polyethylene terephthalate molding compositions containing(A) about 20 to about 80% by weight of polyethylene terephthalate;(B) about 5 to about 50% by weight of a reinforcing fiber; and(C) about 6 to about 60% by weight of a copolyether-ester consisting essentially of(a) long-chain ester units having the formula: ##STR1## wherein G is the divalent radical remaining after removal of the terminal hydroxyl groups from a poly(alkylene oxide) glycol having a number-average molecular weight of about 400 to about 6000; and R is the divalent radical remaining after removal of the carboxyl groups from a dicarboxylic acid; and(b) short-chain ester units having the formula: ##STR2## wherein D is the divalent radical remaining after removal of the hydroxyl groups from a low molecular weight diol having a molecular weight of less than about 250; and R is as defined above;with the proviso that the short-chain ester units constitute about 40 to about 90% by weight of the polyether-ester, and the long-chain

  • Patent number: 4021396
    Abstract: The aqueous coating composition of this invention is useful as a formable coating for the interior and exterior of cans and contains the following compatible mixture of film-forming constituents:(a) an acrylic polymer that has at least two or more reactive sites per chain such as carboxyl, hydroxyl, epoxide, methylol, amine or amide and has a number average molecular weight above 10,000 and a glass transition temperature of -20.degree. C. to +60.degree. C.; and(b) an epoxy resin that has at least one epoxide group in combination with at least one hydroxyl group or epoxide group or combination thereof per polymer chain and has a number average molecular weight of 300 to 20,000;Wherein the film-forming constituents in the fully cured state have a brittle ductile transition temperature of -40.degree. C. to +20.degree. C. measured at an elongation rate of 10% per minute.

  • Patent number: 3941857
    Abstract: A composition comprising a vinylchloride/olefin copolymer and a small amount of an epoxy resin is provided. The epoxy resin reacts with residual surfactants in the copolymer on heating. Coatings of the composition have satisfactory hot water resistance. Coatings prepared from the copolymer without epoxy resin have inconsistant performance as to hot water resistance with a substantial tendency toward pitting as shown by "blushing.
