  • Non-exuding thermoplastic elastomers
    Patent number: 5543489
    Abstract: The invention relates to a composition based on a thermoplastic elastomer comprising polyether sequences in which the amount of matter extractable by ethanol is less than a value sufficient to prevent exudation. Thermoplastic elastomer block copolymer compositions according to the invention comprise polyether blocks and blocks selected from the group consisting of polyamide blocks and polyester blocks, said copolymer compositions incorporating a quantity of terpolymer, selected from the group consisting of ethylene/unsaturated acid ester/unsaturated dicarboxylic acid anhydride terpolymer and ethylene/unsaturated acid ester/unsaturated glycidyl monomer terpolymer, sufficient to prevent exudation of polyamide, polyester, or polyether oligomers or impurities.
