    摘要： The invention relates to elastomeric copolymers of an aromatic vinyl compound and a conjugated diene, suitable for use in the tread portion of a pneumatic tire, which copolymers have a vinyl content of at least 30% by weight and comprise at least two polymer chains coupled to one another having a differential content of the aromatic vinyl compound at the ends of the copolymer which changes in a portion of not more than 5% of each polymer chain from a first value to a second value which is at least 25 percentage points higher than the first value, and said portion lies within the free terminal 10% portion of the copolymer chain (as determined by monomer conversion); their preparation and their use in tread portions of tires. The process of the invention is characterized by employing as structure modifier a compound of formulaR.sup.1 --O--CH.sub.2 --CH.sub.2 --O--R.sup.2 (I)wherein R.sup.1 and R.sup.2 are the same or different C.sub.2-18 alkyl groups, and on completion of polymerization, polymer chains are coupled by means of a coupling agent. The copolymers are characterized by containing a region extending over at least 50% of the polymer chain (as determined by monomer conversion) wherein the differential content of the aromatic vinyl compound in the polymer chain is at least 5% by weight less than the average content of the aromatic vinyl compound in the copolymer.

    摘要： An elastomeric homopolymer or copolymer is reacted with or, in effect, grafted onto an unsaturated polyester and the reaction product or graft polymer may then be used in a thermosetting unsaturated polyester resin composition. The chemical linkage between the elastomeric polymer and the unsaturated polyester is a cyclic structure comprising 6 carbon atoms. The chemical bond is achieved by first treating the elastomeric polymer to incorporate a conjugated diolefin structure and then adding the conjugated diolefin group to an ethylenically unsaturated group in the polyester or a monomeric dienophile. When added to a monomeric dienophile, the polyester is then grafted onto the elastomeric polymer at the site of the monomeric dienophile. The chemical linkage or bonding occurs through a 4+2 Diels Alder addition. The reaction or grafting effectively incorporates an elastomer segment into the thermosetting polyester resin composition and imparts improved surface characteristics and impact resistance without risk of destructive phase separation which has, heretofore, occurred when thermoplastic elastomers were incorporated into thermosetting polyester resin compositions.
