Abstract:
Thermoplastic moulding compositions and mouldings of: A. FROM 95 TO 5% BY WEIGHT OF POLYCARBONATES OF DIHYDRIC PHENOLS, AND B. FROM 5 TO 95% BY WEIGHT OF A GRAFT COPOLYMER OF STYRENE AND ACRYLONITRILE ON AN ACRYLIC ACID ESTER HOMOPOLYMER AND/OR COPOLYMER.
Abstract:
GRAFT COPOLYMERS OF A DIENE POLYMER AS A BASE AND A STYRENE TYPE AND AN ACRYLONITRILE TYPE MONOMER ARE PRODUCED WITH A WATER-SOLUBLE, ALIPHATIC AZO-COMPOUND AS A CATALYST.
Abstract:
in which R1 represents H or CH3; R2 represents H or an alkyl group having 1 to 8 carbon atoms; R3 represents H or an alkyl group or a carboxyalkyl group having 1 to 10 carbon atoms; and R4 represents H or CH3, and 95 TO 50 PARTS BY WEIGHT, OF A POLYMERISED MIXTURE OF I. STYRENE, NUCLEAR OR SIDE CHAIN ALKYL STYRENE, METHACRYLIC ACID ALKYL (C1 - C4) ester or mixtures thereof II. ACRYLONITRILE, METHACRYLONITRILE, AN ALKYL (C1 - C4) ester of methacrylic or fumaric acid, or mixtures thereof, IN A WEIGHT RATIO OF (I) : (II) 100 : 0 TO 60 : 40 AT LEAST 20% OF THE TOTAL POLYMERISED MIXTURE BEING GRAFT-POLYMERISED ONTO THE ELASTOMER IN AQUEOUS DISPERSION.
Thermoplastic moulding compositions which comprise: 5 to 50 parts by weight, of an elastomeric copolymer of 94 to 99.5 parts by weight of an acrylic acid alkyl ester having 4 to 10 carbon atoms in the alkyl group and 0.5 to 6 parts by weight of an acrylamide- or methacrylamide-N-alkylol compound of the general formula (I)
Abstract:
PROCESS FOR PRODUCING GRAFT COPOLYMERS FROM STYRENE, SUBSTITUTED STYRENES AND METHYL METHACRYLATE AND FROM ACRYLONITRILE, METHACRYLONITRILE, METHACRYLATES OR MIXTURES THEREOF BY POLYMERISATION IN THE PRESENCE OF AN AZOACYL COMPOUND AS CATALYST.
Abstract:
Thermoplastic-elastic moulding compositions from 5 to 50 percent by weight of a polypentenamer as a grafting base and from 95 to 50 parts by weight of a vinyl or vinylidene compound and a process for producing these compositions by graft polymerizing the vinyl or vinylidene compound in the presence of the polypentenamer e.g. in emulsified form.
