Abstract
Sports equipment incorporate thermoplastic compositions including urethane and a nitroso reaction product of a nitroso compound and a diisocyanate or polyisocyanate. The invention allows for the processing advantages of a thermoplastic urethane with the superior performance characteristics of a cross-linked polyurethane.
Claims39
Sports equipment comprising a thermoset composition, the composition comprising the reaction product of:
- (a) (1) a urethane, or
- (2) a mixture comprising diol or polyol or mixtures thereof, along with diisocyanate or polyisocyanate, or mixtures thereof, or
- (3) a mixture of (1) and (2);
- and
- (b) a nitroso reaction product formed as a reaction product of a nitroso compound and a diisocyanate or a polyisocyanate,
- wherein the nitroso reaction product is characterized by a characteristic temperature at which it decomposes to generate the nitroso compound and diisocyanate or polyisocyanate, and
- wherein the nitroso reaction product is present in an amount sufficient to render the composition thermoset.
Sports equipment comprising a composition, the composition comprising the reaction product of:
- (a) (1) aurethane, or
- (2) a mixture comprising diol or polyol or mixtures thereof, along with diisocyanate or polyisocyanate, or mixtures thereof;
- or
- (3) a mixture of (1) and (2);
- and
- (b) a nitroso reaction product formed as a reaction product of a nitroso compound and a diisocyanate or a polyisocyanate,
- wherein the nitroso reaction product is characterized by a characteristic temperature at which it decomposes to generate the nitroso compound and diisocyanate or polyisocyanate, and wherein the composition further comprises an organic peroxide.
Sports equipment comprising a thermoset composition, the composition comprising the reaction product of:
- (a) (1) a urethane, or
- (2) a mixture comprising diol or polyol or mixtures thereof, along with diisocyanate or polyisocyanate, or mixtures thereof, or
- (3) a mixture of (1) and (2);
- and
- (b) a nitroso reaction product formed as a reaction product of a nitroso compound and a diisocyanate or a polyisocyanate,
- wherein the nitroso reaction product is characterized by a characteristic temperature at which it decomposes to generate the nitroso compound and diisocyanate or polyisocyanate,
- wherein the urethane or the mixture comprising dial or polyol or mixtures thereof along with diisooyanate or polyisocyanate or mixtures thereof, is substantially free of unsaturated hydrocarbons, and
- wherein the nitroso reaction product is present in an amount Sufficient to render the composition thermoset.
