    Abstract: A process for making a copolymeric resin is disclosed. Accordingly, component (a) and component (b) are introduced into an extruder under conditions designed to promote reactive blending therebetween in the presence of a transesterification catalyst. Component (a) is a wet aromatic polycarbonate resin containing moisture in an amount greater than 0.02 weight percent and having units conforming to ##STR1## wherein D is a divalent residue of a dihydroxy compound. Component (b) is a lactone-siloxane block copolymer having structural units conforming to ##STR2## wherein m is 1-90, n is 60-150, R is an alkyl or a phenyl radical, p is 2-12 and q is 2-20. Surprisingly, use of moisture-containing polycarbonate in the process yields a copolymer having good properties, although a corresponding process where the lactone-siloxane block copolymer reactant has a smaller number of repeating units yields inferior product.

    Abstract: A process for rapidly improving the flowability, in pellet form, of a molding composition is disclosed. Accordingly, the crystalline content of an amorphous or a semi-amorphous version of a crystallizable thermoplastic resin is increased by subjecting the resin to infra-red radiation to an extent which induces the formation of crystals in the irradiated amorphous resin or the increase of the level of crystals in the semi-amorphous irradiated resins. The resin modified by the inventive process is rendered more suitable for processing: in dried, pellet-form, the modified resin is characterized by its improved flowability. An article molded from the thus modified resin exhibits better properties than does a corresponding article made from a unmodified resins which has been subjected to similar drying conditions.
