Title
(EN) POLYMERIC COMPOSITION COMPRISING A THERMOPLASTIC ELASTOMER WITH BUTADIENE AND STYRENE BLOCKS AND A COMPATIBLE PLASTICISER
(FR) COMPOSITION POLYMÉRIQUE COMPRENANT UN ÉLASTOMÈRE THERMOPLASTIQUE À BLOCS BUTADIÉNIQUES ET STYRÉNIQUES ET UN PLASTIFIANT COMPATIBLE
Abstract
(EN)
The invention relates to a polymeric composition comprising a) at least one block thermoplastic elastomer comprising at least one elastomer block and at least one thermoplastic block, the one or more elastomer blocks predominantly comprising units originating from butadiene, the one or more thermoplastic blocks being made up of units originating from one or more styrene monomers; b) at least one plasticiser selected from butadiene oligomers, provided that: b1) the molar ratio of 1,2-polybutadiene units in said plasticiser is included in a range ranging from 70% to 130% of the molar ratio of 1,2-polybutadiene units in the elastomer block of the thermoplastic elastomer, and the molar mass of the plasticiser is greater than 1500 g/mol, preferably greater than 2000 g/mol, and less than 50000 g/mol, or even b2) the molar ratio of 1,2-polybutadiene units in the plasticiser is less than 70% or greater than 130% of the molar ratio of 1,2-polybutadiene units in the elastomer block of the thermoplastic elastomer, and the molar mass of the plasticiser is greater than 4000 g/mol, preferably greater than 5000 g/mol, and less than 50000 g/mol.
