Patent number: 5274043Abstract: Blend compositions and process are provided comprising admixing of chlorinated polyvinyl chloride and polyvinyl chloride, each having specified inherent viscosity wherein the difference in the inherent viscosity of the polyvinyl chloride of the blend, measured in similar accordance with ASTM-D1243 is at least 0.2 units higher than the precursor polyvinyl chloride for the chlorinated polyvinyl chloride of the blend. Preferably the I.V. of the polyvinyl halide is from 0.2 to 1.0 units higher with the most preferred difference in I.V. (.DELTA.I.V.) being 0.35 to 0.65 units so as to yield a balance of property improvements including tensile strength, impact resistance, heat distortion temperature and weatherability. The compositions also can further comprise a Tg enhancing agents which otherwise embrittle conventional PVC compounds.Type: GrantFiled: May 9, 1991Date of Patent: December 28, 1993Assignee: The B. F.

Glass fiber reinforced poly(vinyl chloride) blend with improved heat distortion and tensile strength
Patent number: 5008145Abstract: 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.Type: GrantFiled: September 7, 1989Date of Patent: April 16, 1991Assignee: The B. F. Goodrich CompanyInventors: Philip L. Kinson, Edward M. Faber -

Patent number: 4588806Abstract: New forms of polyphenylene ether resin have been discovered that are characterized by two distinct molecular weight distributions as determined by gel permeation chromatography. Two maxima are exhibited, one of which corresponds to a polystyrene equivalent molecular weight greater than 30,000, the other of which is less than 30,000. The polymers, which may be termed "bimodal", have improved melt flow in comparison with conventional (unimodal) polyphenylene ether resins.Type: GrantFiled: November 8, 1984Date of Patent: May 13, 1986Assignee: General Electric CompanyInventors: David F. Aycock, Philip L. Kinson

Patent number: 4564656Abstract: A process for the preparation of a graft product of polyphenylene ether and diene rubber from a starting mixture of the two polymers is described. The process can be extended by further polymerizing an alkenyl aromatic compound such as styrene in the presence of the graft product to form a novel terpolymer. The polymers which result from the process are useful as impact resistant modifiers for various engineering thermoplastics, including polyphenylene ether resins.Type: GrantFiled: February 26, 1985Date of Patent: January 14, 1986Assignee: General Electric CompanyInventors: Glenn D. Cooper, deceased, Philip L. Kinson

Patent number: 4058570Abstract: Brominated biphenols are produced by a bromination process which comprises reacting bromine with a 3,3', 5,5'-tetrasubstituted diphenoquinone at a temperature below about +20.degree. C. in the presence of an inert diluent, evolving hydrogen bromide gas at a temperature of about +20.degree. C. or lower, heating the resulting reaction mixture at elevated temperatures to complete the bromination reaction and recovering the desired 2,2',6,6'-tetrabromo-3,3',5,5'-tetrasubstituted-4,4'-biphenol. The biphenol products of the process can be used as antioxidants, as monomeric starting materials for polymeric halogenated organic compounds which are fire retardant as well as monomeric flame retardant additives for polymeric compositions useful in molding, coating and insulating various articles of manufacture.Type: GrantFiled: May 7, 1976Date of Patent: November 15, 1977Assignee: General Electric CompanyInventors: Philip L.
