Abstract

Es objetivo de la invención el uso de copolímeros de vinilacetato como aditivos para reducir el grado de contracción (aditivos de bajo perfil) en sistemas de curado en frío para la fabricación de materiales compuestos, caracterizado por que se usan copolimerizados de vinilacetato de 40 a 95 % en peso de vinilacetato y 5 a 60 % en peso de uno o varios comonómeros del grupo que contiene vinilésteres de ácidos carboxílicos ramificados o no ramificados con 3 a 20 átomos de C y ésteres de ácido metacrílico y ésteres de ácido acrílico de alcoholes ramificados o no ramificados con 2 a 15 átomos de C, en el que los datos en % en peso se refieren al peso total de los comonómeros y totalizan 100 % en peso.
