A low molecular weight co-oligomer containing styrene and &#x3b1;-methyl styrene in bound form and having a ring and ball softening point not greater than 50&#xb0; C. is useful in modifying the properties of a diene elastomer-based curable rubber composition capable of being used to manufacture tire treads.

Curable rubber compositions containing styrene/alpha-methyl styrene co-oligomers

A modified polymer includes a diene-based polymeric chain and at least one end terminated with a blocked isocyanate group. The blocked isocyanate group may be the reaction product of an isocyanate and a blocking agent, and the blocking agent is selected, such that the modified polymer deblocks at temperatures of at least 100 C. An aqueous emulsion of the modified polymer may be provided that may be surfactant-free. The emulsion may be combined with one or more latexes to provide a treatment solution for a fabric or fiber that does not require the use of resorcinol and formaldehyde. Once treated and dried, the fabric or fiber may be used to impart tensile strength to rubber products, such as tires, air springs, flexible couplings, power transmission belts, conveyor belts, and fluid routing hoses.

Modified polymers and stable emulsions comprising the same

A farnesene polymer is provided having a glass transition temperature greater than zero degrees Celsius that is obtained by combining a farnesene monomer and a solvent and optionally adding one or more vinyl aromatic comonomers to provide a monomer feed and polymerizing the monomer feed with a Friedel-Crafts catalyst. The farnesene polymer may be included as a resin in a rubber composition for tire applications.
