Title: TRIBLOCK DIENE ELASTOMER WHERE THE CENTRAL BLOCK IS A POLYETHER BLOCK AND THE CHAIN ENDS ARE AMINE-FUNCTIONALISED
Abstract:
The invention relates to a triblock diene elastomer where the central block is a polyether block with a number average molecular mass of between 150 and 5000 g/mol and is connected to each of the side blocks by a silicon atom, and at least 70 molar % of the chain ends, in relation to the number of moles at the end of the chain, is functionalised by an amino function.
