Title (EN) PROCESS FOR LASER WELDING POLYESTER COMPOSITIONS
(FR) TRAITEMENT DE COMPOSITIONS A BASE DE POLYESTERS POUR LE SOUDAGE AU LASER
Abstract: front page image
(EN)A process for laser welding objects formed from compositions comprising thermoplastic polyester compositions that are resistant to thermal shock. The compositions comprise thermoplastic polyesters and an epoxidized block copolymer derived from at least one vinyl aromatic compound and at least one conjugated diene.
(FR)L'invention concerne un procédé de soudage au laser d'objets formés à partir de compositions, notamment de compositions à base de polyesters thermoplastiques résistant à un choc thermique. Lesdites compositions comprennent des polyesters thermoplastiques et un copolymère séquencé époxydé dérivé d'au moins un composé vinyle aromatique et d'au moins un diène conjugué.
