Abstract: A method and system for introducing a new material into a product design system wherein the system receives basic material use information from a requesting party and determines whether a new material introduction (NMI) is necessary for acquiring approval to use the material. If an NMI is required, the system receives details of the NMI and electronically notifies appropriate approval departments of the NMI. The various approval departments are simultaneously supplied with specific NMI information. Once the NMI information has been reviewed, the system receives approval determinations from the various departments. If approvals have been received from all departments, the requesting party is notified of the approval and a database of NMI's is updated to reflect the approved NMI. However, if the NMI is not approved by all departments, the requesting party is so notified and the NMI database is not updated.

Abstract: The invention relates to a material which comprises at least 20% of polyphenylene ether and which comprises as a flame-retardant 0.05-10% by weight of a boron compound, for example, boric acid, B.sub.2 O.sub.3, borate, salts or borate esters related to the polyphenylene ether, as well as, optionally, a plasticiser and further conventionally used additives.

Abstract: The invention relates to polymer mixtures which comprise a polyphenylene ether, a polyoctenylene and TiO.sub.2 or BaSO.sub.4. The presence of TiO.sub.2 or BaSO.sub.4 leads to an improvement of the mechanical properties.

Abstract: The invention relates to a polymer mixture which comprises a polyphenylene ether, a block copolymer, and a phosphate ester in a given ratio by weight. The polymer mixture according to the invention is particularly suitable as a material for cable sheaths.

Abstract: The properties of polymer mixtures which comprise an aromatic polycarbonate, an aromatic polyester and a core-shell polymer having an acrylate core, can be improved by using a core-shell polymer having a particle size of less than 0.2 micrometers.

Abstract: The properties of polymer mixtures which comprise a polyphenylene ether and a polyvinyl aromatic compound can be improved by the simultaneous addition of an organic metal sulphonate compound and a block copolymer. In particular a combination of a good impact strength and a good resistance against agressive media under mechanical stresses (environmental stress) cracking resistance "ESCR") is obtained. This also applies to polymer mixtures having a high content of titanium dioxide.

Abstract: The invention relates to polymer mixtures which comprise a polyphenylene ether which have been stabilized with oxalyldihydrazide against oxidative degradation.

Abstract: A polymer mixture comprising(a) a base resin selected from the group consisting of polyphenylene ether resins and polyphenylene ether modified with alkenyl aromatic resins; and(b) an amount of antistatic agent effective for improving the antistatic character of said polymer mixture wherein said antistatic agent is a compound of the formula R--SO.sub.3 X, where R is an alkyl or aralkyl radical having 5 to 25 carbon atoms and X is an alkali metal.

Abstract: The present invention deals with polymer blends comprising a polyphenylene ether and optionally polystyrene or a rubber modified polystyrene. It has been found that the addition of an alkyl or aralkyl-sulfonate to such blends improves the environmental stress cracking resistance of such blends.

Abstract: A thermoplastic composition having improved resistance to discoloration upon exposure to light, comprising:a thermoplastic resin base polymer; andat least one dye capable of bleaching upon exposure to light in an amount effective for compensating for a change in color of said thermoplastic resin base polymer upon exposure to said light.
