摘要： This invention relates to a tire tread compound that is easily processable which can be used to improve the treadwear, rolling resistance and traction characteristics of tires. The tire tread compounds of this invention are a blend of tin-coupled polybutadiene, high vinyl polybutadiene and natural rubber. This blend of low glass transition temperature rubber and high glass transition temperature rubber is surprisingly easy to process which makes the concept of this invention commercially feasible. Thus, the tire tread compounds of this invention can be utilized in making tires having greatly improved traction characteristics and treadwear without sacrificing rolling resistance. These improved properties may be due, in part, to better interaction and compatibility with carbon black and/or silica fillers. The polybutadiene in the blend can be asymmetrical tin-coupled to further improve the cold flow characteristics of the rubber blend. Asymmetrical tin coupling in general also leads to better processability and other beneficial properties. This invention more specifically discloses a tire tread rubber composition which is comprised of (1) from about 20 phr to about 60 phr of tin-coupled polybutadiene rubber, (2) from about 20 phr to about 60 phr of a rubber selected from the group consisting of natural rubber and synthetic polyisoprene and (3) from about 5 phr to about 40 phr of high vinyl polybutadiene rubber.
摘要翻译：本发明涉及一种易于加工的轮胎胎面胶，其可用于改善轮胎的胎面磨损，滚动阻力和牵引特性。本发明的轮胎胎面胶料是锡偶合的聚丁二烯，高乙烯基聚丁二烯和天然橡胶的混合物。这种低玻璃化转变温度橡胶和高玻璃化转变温度橡胶的混合物令人惊奇地易于加工，这使得本发明的概念在商业上可行。因此，本发明的轮胎胎面胶料可用于制造具有极大改善的牵引特性和胎面磨损的轮胎，而不会牺牲滚动阻力。这些改进的性质可能部分是由于与炭黑和/或二氧化硅填料的更好的相互作用和相容性。共混物中的聚丁二烯可以是不对称的锡偶联，以进一步改善橡胶共混物的冷流特性。不对称锡偶联一般也会导致更好的加工性能和其他有益的性能。本发明更具体地公开了一种轮胎胎面橡胶组合物，其包含（1）约20phr至约60phr的锡偶联的聚丁二烯橡胶，（2）约20phr至约60phr的选自下组的橡胶：由天然橡胶和合成聚异戊二烯组成，（3）约5phr至约40phr的高乙烯基聚丁二烯橡胶。

These isoprene-butadiene rubbers are made by reacting an isoprene-butadiene rubber having a glass transition temperature which is within the range of about -50.degree. C. to about 0.degree. C. with a tin compound of the formula SnR.sub.3 X, wherein R represents an alkyl group and wherein X represents a halogen. This invention more specifically discloses a tire tread rubber composition which is comprised of (1) about 60 phr to about 95 phr of an isoprene-butadiene rubber having a glass transition temperature which is within the range of about -50.degree. C. to about 0.degree.

摘要： The neodymium catalyst system prepared by the technique of this invention can be used in the polymerization of isoprene monomer into synthetic polyisoprene rubber having an extremely high cis-microstructure content and high stereo regularity. This polyisoprene rubber will crystallize under strain and can be compounded into rubber formulations in a manner similar to natural rubber. This invention more specifically discloses a process for the synthesis of polyisoprene rubber which comprises polymerizing isoprene monomer in the presence of a neodymium catalyst system, wherein the neodymium catalyst system is prepared by a process that comprises (1) reacting a neodymium carboxylate with an organoaluminum compound in an organic solvent to produce neodymium-aluminum catalyst component, and (2) subsequently reacting the neodymium-aluminum catalyst component with an elemental halogen to produce the neodymium catalyst system, wherein the neodymium catalyst system is void of nickel-containing compounds.
