  • Patent number: 5037937
    Abstract: Novel polycarbonate resins, a process for production of said polycarbonate resins, and compositions containing said polycarbonate resins and glass fibers as major components are disclosed. The polycarbonate resins have: (1) a repeating unit (I) represented by the general formula (A): ##STR1## and a repeating unit (II) represented by the general formula ##STR2## (all the symbols are as defined in the appended claims); (2) a pentahalogenophenoxy group as the end group thereof; and (3) a viscosity average molecular weight of at least 5,000. The polycarbonate resins are excellent in all of flame retardance, fluidity, impact resistance and transparency. Thus the polycarbonate resins and compositions containing them are useful for production of, e.g., moldings for which all the above characteristics are required.

  • Patent number: 5008145
    Abstract: A high temperature PVC resin blend is made by blending from 60 to 85 parts PVC with no more than 40 parts of a ("alpha-SAN") copolymer of alpha-methyl styrene ("AMS"), styrene ("S") and acrylonitrile ("AN"), and less than 20 parts by wt additives including stabilizers, antioxidants, lubricants, and processing aids. In addition, an impact modifier may be added. The blend with particularly sized glass fibers, may be thermoformed at an elevated processing temperature and pressure, to provide a reinforced composite in which the PVC is covalently bonded to the glass fiber. The composite has a substantially higher HDT and equivalent tensile strength, compared to that of a similarly reinforced, unblended PVC composite, without sacrificing the novel composite's other desirable physical properties.
