ABSTRACT:
The disclosure of this application is directed to unsaturated polyester compositions, containing as a low-profile additive a carboxyl containing thermoplastic polymer of a vinyl ester of an aliphatic, saturated monocarboxylic acid, which have particular utility in molding applications to form aesthetically attractive thermoset articles characterized by excellent physical properties, as for example, impact strength and by excellent surface properties such as excellent smoothness and gloss, excellent receptiveness to paints and excellent reproduction of the surface contours of the mold in which they are formed into shaped, thermoset articles.
