Title (EN) UNSATURATED POLYESTER RESIN COMPOSITIONS CONTAINING COMPATIBLE COMPOUNDS
(FR) RESINES DE POLYESTER NON SATUREES CONTENANT DES COMPOSES COMPATIBLES
Abstract:
(EN) A sheet molding composition is disclosed which includes a four component resinous system which comprises (a) an unsaturated polyester comprising a polycondensation product of one or more dihydric alcohols and one or more ethylenically unsaturated polycarboxylic acids; (b) one or more low-profile additives which are thermoplastic polymers which cause phase separation and porosity during the curing reaction; (c) one or more olefinically unsaturated monomers which copolymerize with the unsaturated polyester; and, (d) one or more compatible components comprising at least one compound containing one or more polyoxyethane substituents. The compatible components remain compatible when the polyester and monomer cure and impart improved surface characteristics when added to low-profile resin systems.
(FR) On décrit un préimprégné comprenant un système résineux à quatre éléments structuraux qui comporte (a) un polyester non saturé comprenant un produit de polycondensation d'un ou plusieurs dialcools et un ou plusieurs acides polycarboxyliques non saturés par éthylène; (b) un ou plusieurs additifs peu contractibles qui sont des polymères thermoplastiques qui provoquent la porosité et la séparation de phase pendant la réaction de cuisson; (c) un ou plusieurs monomères non saturés par oléfine qui se copolymérisent avec le polyester non saturé; et (d) un ou plusieurs éléments structuraux compatibles comprenant au moins un composé qui contient un ou plusieurs produits de remplacement au polyoxyéthane. Les éléments structuraux compatibles demeurent compatibles lorsque le polyester et le monomère durcissent, et donnent des caractéristiques de surface améliorées lorsqu'ils sont ajoutés aux systèmes résineux peu contractibles.
