Title

Abstract
(EN)
A foaming composition useful to make an extruded foam is comprised of: a copolymer of a vinylidene aromatic monomer and an unsaturated compound containing nucleophilic groups, a copolymer of vinylidene aromatic monomer and an unsaturated compound having electrophilic groups; and a blowing agent. The foaming composition may be made into a foam by heating the foaming composition to a temperature sufficient to melt and react said copolymers to form a chain extended/branched copolymer and extruding the foaming composition from a higher pressure to a lower pressure to form an extruded foam comprised of the chain extended/branched copolymer. The foam is comprised of a chain extended/branched copolymer that is the reaction product of (i) a copolymer of one or more vinylidene aromatic monomers and one or more unsaturated compounds containing nucleophilic groups, and (ii) a copolymer of one or more vinylidene aromatic monomers and one or more unsaturated compounds having electrophilic groups.

L’invention concerne une composition moussante utile pour fabriquer une mousse extrudée comprenant : un copolymère d'un monomère aromatique de vinylidène et d'un composé insaturé contenant des groupes nucléophiles, un copolymère de monomère aromatique de vinylidène et un composé insaturé ayant des groupes électrophiles ; et un agent d'expansion. La composition moussante peut être transformée en mousse par chauffage de la composition moussante à une température suffisante pour faire fondre et faire réagir lesdits copolymères pour former un copolymère à chaîne étendue/ramifiée et extruder la composition moussante d'une pression supérieure à une pression inférieure pour former une mousse extrudée composée du copolymère à chaîne étendue/ramifiée. La mousse est constituée d'un copolymère à chaîne étendue/ramifiée qui est le produit de réaction de (i) un copolymère d'un ou plusieurs monomères aromatiques de vinylidène et d'un ou plusieurs composés insaturés contenant des groupes nucléophiles, et (ii) un copolymère d'un ou plusieurs monomères aromatiques de vinylidène et d'un ou plusieurs composés insaturés ayant des groupes électrophiles.
