摘要： The present invention is directed to a rubber composition comprising an elastomer, a filler, and a block-copolymer. According to the invention, the block-copolymer comprises (i) an elastomer block and (ii) a thermoplastic block comprising a poly alkylacrylate, wherein the alkylacrylate comprises a polycyclic substituent at its single bonded oxygen atom. Moreover, the present invention is directed to a block-copolymer.

摘要： The present invention is directed to a synthetic polyisoprene which comprises isoprene repeat units comprising 1,4 isoprene repeat units and 3,4 isoprene repeat units. At least 5% of all isoprene repeat units of the synthetic polyisoprene are 3,4 isoprene repeat units and at least 96% of all 1,4 isoprene repeat units of the synthetic polyisoprene are cis 1,4 isoprene units. Moreover, the invention is directed to a method of synthesizing such a polyisoprene and a rubber composition comprising the synthetic polyisoprene.
