摘要:
A composition containing a graft polymer based on acrylonitrile/ethylene propylene rubber/styrene (AES) and an additive is disclosed. The additive is one which increases the “Δsoft phase” of the composition making it possible to produce moldings with improved toughness at low temperatures, without substantially changing the melt volume rate.
摘要:
The present invention relates to polymer blends containing a component selected from the group poly(ester)carbonates, graft polymers or mixtures thereof, polyalkylene naphthalate as the second component optionally together with a further component selected from the group of vinyl (co)polymers, polyalkylene terephthalates or mixtures thereof, wherein mixtures of polycarbonate, polyalkylene naphthalate and optionally polyalkylene terephthalate contain no tetrafluoroethylene polymer.

摘要:
A molding composition containing a graft polymer is disclosed. The graft is a product of a free-radical emulsion polymerization of resin-forming vinyl monomers in the presence of rubber present in latex form having a glass transition temperature of ≦0° C. using an initiator combination comprising a persulfate compound and a redox initiator system. The process for preparing the graft polymer entails adding the persulfate compound at the beginning of the graft polymerization reaction and a later addition of the redox initiator. The composition that features good gloss and flowability is suitable for the preparation of molded articles.

Thermoplastic moulding compositions containingA. a thermoplastic polymer andB. 0.1 to 50% by weight, with respect to A, of an inorganic substance with an average particle diameter of 0.1 to 100 nm,and the use of superfine inorganic substances as defined by B for increasing the X-ray contrast of thermoplastic moulding compositions comprising A and B.
摘要:
This invention relates to graft polymers of the ABS type which are produced in emulsion, and to thermoplastic molding compositions which are based thereon and which exhibit a very considerably increased notched bar impact strength compared with known ABS molding compositions and which at the same time exhibit high hardness values or high modulus values and good thermoplastic processability.
摘要:
This invention relates to halogen-free flame retardant thermoplastic moulding compositions prepared from polycarbonate and graft polymer, which may optionally contain thermoplastic copolymer and/or polyalkylene terephthalate.The flame retardant used is a synergistic combination of silicone resin and polyphenylene oxide.
