摘要： A clear impact resistant molding compound which does not become cloudy under either the influence of heat or moisture or on weathering and is composed according to the invention of:A) 10 to 90 percent by weight of a continuous rigid phase, essentially of methyl methacrylate, having a glass transition temperature greater than 70.degree. C. andB) 90 to 10 percent by weight of an elastomeric phase, distributed in the rigid phase and partly bound thereto, having a glass transition temperature below -10.degree. C., an average particle size of the elastomeric phase below 130 nm, and an inhomogeneity, U, of the elastomeric phase particle size of less than 0.5, comprising at least 50 percent by weight of B) of a lower alkyl acrylate and 0.5-5 percent by weight of a graft cross linking agent or an at least trifunctional cross linking agent,C) not more than 0.05 percent by weight of water soluble components,where U=D.sub.w.sup.3 /D.sub.n.sup.3- 1 D.sub.w and D.sub.n are, respectively the weight average- and number average-values of the particle size,films prepared from such a molding compound;multilayer shaped bodies wherein at least one layer is of such a molding compound;methods for making such molding compounds, films, and shaped bodies.
