Abstract
La presente invención se refiere a una dispersión polimerica acuosa que contiene un poliuretano dispersable en agua y un polímero de vinilo, el poliuretano siendo el producto de reacción de un extendedor de cadena que contiene hidrógeno activo con un prepolímero de poliuretano terminado en isocianato dispersble en agua derivado de un componente de poliisocianato que contiene cuando menos 5 por ciento por peso de diisocianato de 2,4'-difenilmetano.The present invention relates to an aqueous polymer dispersion containing a water dispersible polyurethane and a vinyl polymer, the polyurethane being the reaction product of an active hydrogen containing chain extender with a water dispersible isocyanate terminated polyurethane prepolymer derived from a polyisocyanate component containing at least 5 percent by weight 2,4'-diphenylmethane diisocyanate.
