Claim Text:
1. A latex comprising water and a styrenic block copolymer, wherein the styrenic block copolymer has 2 or more poly(vinyl aromatic) blocks, said poly(vinyl aromatic) blocks are a polystyrene block, containing less than 5 wt % of copolymerizable monomer, based on the weight of poly(vinyl aromatic) block and at least one block of polymerized conjugated diene, said conjugated diene is a polyisoprene block, containing less than 5 wt % of copolymerizable monomer, based on the weight of block polymerized conjugated diene, wherein the styrenic block copolymer has a weight average molecular weight of 170,000 to 220,000, the poly(vinyl aromatic) blocks have a weight average molecular weight ranging from 9,000 to 14,000, and the content of poly(vinylaromatic) blocks in the styrenic block copolymer ranges from 9 to 14% wt, based on the total styrenic block copolymer, and a vulcanising agent.
