ABSTRACT:
This invention provides a liquid, polymerizable composition of matter, suitable for molding fibrous reinforced articles with exceptionally smooth surfaces, said composition being curable under heat and pressure to form a rigid, cured product which is characterized by an optically heterogeneous appearance. The composition comprises a thermoplastic cellulose ester, and .alpha.,.beta.-ethylenically unsaturated polymerizable polyester having a molecular weight per double bond factor of 150 to 186, and a monomer containing a CH.sub.2 .dbd.C< group copolymerizable with the unsaturated polyester.
