Patent number: 4256862Abstract: Modified polyaryl-sulphones comprise one or more polyaryl-sulphones and one or more ammonium salts or metal salts of organic sulphonic acids, preferably 0.01 to 5% by weight, relative to the total weight of polyaryl-sulphone plus salt of sulphonic acid, of the one or more organic sulphonic acid salts. These simply produced modified polyaryl-sulphones do not suffer from embrittlement under load, and susceptability to stress-cracking under the influence of solvents and of solutions of unsaturated polyester resins experienced by unmodified polyaryl-sulphones. The modified polyaryl-sulphones are particularly suitable for the production of containers, tubes, sheets and films.Type: GrantFiled: March 7, 1979Date of Patent: March 17, 1981Assignee: Bayer AktiengesellschaftInventors: Rudolf Binsack, Joachim Wank, Eckart Reese

Patent number: 4186154Abstract: The present invention relates to mixtures comprising about 60% by weight to 5% by weight of aromatic polycarbonates which have a Mw between about 60,000 and 120,000 (component A) and about 40% by weight to 95% by weight of aromatic polycarbonates which have a Mw between about 28,000 and 40,000 (component B), as well as to processes for their preparation and their use for the production of shaped articles. The melt which can be prepared from the mixtures according to the invention has a high stability and the films obtainable therefrom have a high resistance towards stress cracking.Type: GrantFiled: June 19, 1978Date of Patent: January 29, 1980Assignee: Bayer AktiengesellschaftInventors: Rudolf Binsack, Eckart Reese, Erhard Tresper, Joachim Wank

Branched polyaryl-sulphone/polycarbonate mixtures and their use for the production of extruded films
Patent number: 4152367Abstract: The present invention is concerned with mixtures of branched polyaryl-sulphone and aromatic polycarbonates having Mw in excess of about 60,000. These mixtures are particularly suitable for the production of extruded film although the polycarbonate itself is of too high a molecular weight to be conveniently extruded by itself. These films display superior stress-cracking properties and resistance to unsaturated polyester resins compared to similar blends with lower molecular weight polycarbonates.Type: GrantFiled: July 25, 1978Date of Patent: May 1, 1979Assignee: Bayer AktiengesellschaftInventors: Rudolf Binsack, Eckart Reese, Joachim Wank -
Patent number: 4140730Abstract: A polycarbonate film having improved flame resistance and good stress-corrosion-cracking resistance is prepared from a solution of a mixture of a low molecular weight polycarbonate containing at least about 5% by weight halogen and a higher molecular weight polycarbonate prepared from bisphenol containing at least 90 mol percent bisphenol A. The novel film can be used to advantage for self-supporting electrical insulating films.Type: GrantFiled: June 26, 1978Date of Patent: February 20, 1979Assignee: Bayer AktiengesellschaftInventors: Rudolph Binsack, Manfred Grundmeier, Eckart Reese, Hugo Vernaleken
