Abstract:
Modified thermoplastic hydrocarbon thermoplastic resins are provided, as well as methods of their manufacture and uses thereof in rubber compositions. The modified thermoplastic resins are modified by decreasing the relative quantity of the dimer, trimer, tetramer, and pentamer oligomers as compared to the corresponding unmodified thermoplastic resin polymers, resulting in a product that exhibits a greater shift in the glass transition temperature of the elastomer(s) used in tire formulations. This translates to better viscoelastic predictors of tire tread performance, such as wet grip and rolling resistance. The modified thermoplastic resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the modified thermoplastic resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, snow performance, and wet braking performance.

Claim (Index 11):
A composition, comprising:\n about 10 to about 90 weight percent of at least one polymer, about 5 to about 70 weight percent of at least one modified thermoplastic resin, about 0 to about 60 weight percent of at least one thermoplastic tackifying resin, about 0 to about 50 weight percent of at least one wax, about 0 to about 60 weight percent of at least one oil or plasticizer, about 0.5 to about 3 weight percent of at least one stabilizer, and about 0 to about 70 weight percent of at least one filler, wherein the composition is non-vulcanized, wherein the at least one modified thermoplastic resin has a glass transition temperature (Tg) of between \u221250\u00b0 C. and 160\u00b0 C., and wherein the at least one modified thermoplastic resin possesses the properties of formula I: S = ( T g M z ) / [ Oligomer \ue89e \u00d7 ( 1 - T 10 T max ) ] I wherein:\n Tg is the glass transition temperature of the at least one modified thermoplastic resin; \n Mz is the z-average molecular weight of the at least one modified thermoplastic resin; \n Oligomer is the fraction of oligomer present in the at least one modified thermoplastic resin as measured by high resolution thermal gravimetric analysis (TGA) or gel permeation chromatography (GPC); \n T 10  is the temperature at which the at least one modified thermoplastic resin loses about 10% of its weight as measured by high resolution TGA; \n T max  is the temperature of the maximum first derivative value of the at least one modified thermoplastic resin as measured by high resolution TGA; \n wherein the value of S is greater than or equal to 2 and less than 50,000 when Oligomer is determined by GPC, or greater than or equal to 5 and less than 10,000 when Oligomer is determined by high resolution TGA; and wherein the value of Mz is less than or equal to 9,000 g/mol.
