Abstract:
The invention relates to a process for preparing a thermoplastic resin comprising the following steps: a) mixing: •a thermoplastic copolyester (A) having a shore A hardness of less than 95; and •a silicone elastomer (B) comprising a polydiorganosiloxane gum having a plasticity of at least 30 and having on average at least 2 alkenyl groups per polymeric chain and optionally a reinforcing agent in the range of 0 to 50 wt % based on the weight of the polydiorganosiloxane gum; and •a radical initiator (C) in an amount of 0.01 to 5 wt % based on the weight of the silicone elastomer; and •optionally an adhesion additive (D); wherein the weight ratio of the silicone elastomer to the thermoplastic copolyester (B:A) is from 15:85 to 99.5:0.5; b) dynamically vulcanizing the silicone elastomer in the thermoplastic copolyester at an elevated temperature. The invention also relates to a thermoplastic resin itself.
