    摘要: A process for preparing a thermoplastic, randomly branched aromatic polycarbonate is disclosed which comprises reacting a carbonate precursor, a dihydric phenol, and a dianhydride branching agent and maintaining the resultant reaction medium at a pH of from about 9 to about 12 to thereby produce a thermoplastic randomly branched aromatic polycarbonate.

    摘要: An embodiment assembly for the impregnation of a continuous length of fibers comprises a convex surface and a non-convex surface over which the length of fibers is drawn under tension. The pressure of impingement on the surfaces alternately separates and consolidates the fibers in sequence during their impregnation with the resin, to obtain a complete and homogeneous impregnation.

    摘要: Thermoplastic randomly branched copolyester-carbonate resin containing from about 40 mole percent to about 90 mole percent ester bonds which is particularly suited for blow molding operations. This branched copolyester-carbonate resin is obtained by reacting a carbonate precursor, at least one dihydric phenol, at least one ester forming reactive derivative of a difunctional carboxylic acid, and a polyfunctional aromatic branching agent.

    摘要: Apparatus for the impregnation of a continuous length of multifilament or multifiber yarns with a molten thermoplastic polymeric resin includes a pair of convex/concave (mating) surfaces for spreading the multifilaments or multifibers apart during their immersion in a bath of the molten resin. The shape, configuration and location of the surfaces facilitates homogeneous impregnation, particularly with highly viscous metls, to produce a uniform and thorough encapsulation of the filaments or fibers.
