Abstract: Electrically and/or thermally conductive reinforced compositions convertible to reinforced components are disclosed. The compositions comprise a polymeric material of little or no conductivity and high strength, metal plated composite fibers having a conductive semimetallic core and a thin, firmly adhered layer of an electrodepositable metal coating on said core. The metal coated composite fibers will not lose their conductive coatings during normal processing and provide conductivity without reducing the physical properties of the polymeric material. The compositions of the invention are convertible to conductive components such as laminate prepregs, surface plys for laminates, conductive adhesives, conductive inks, and conductive elastomeric gaskets. The components can be incorporated in improved articles such as structural parts for transportation vehicles, printed circuit boards, lighting shields and molded articles.

The treated articles in general exhibit a T-peel strength of 1 in. lb./in..sup.2 and greater, which is far in excess of the peel strengths typical of the untreated article.

Abstract: Copolyetherimides having random units in the structure and characterized by good transparency after molding are prepared by a process in which a dianhydride and a diamine are reacted at a temperature of at least 100.degree. C. to initiate polymerization, followed by the addition of a second anhydride and continuing the polymerization at the elevated temperature. Preferred features include conducting the reaction in a solvent and in the presence of a chain stopper, such as phthalic anhydride.

Abstract: Reinforced thermoplastic compositions are provided comprising a high molecular weight linear polyester, such as poly(1,4-butylene terephthalate) in combination with a reinforcing agent and a minor proportion of an alkylhydroxyphenylalkanoyl-hydrazine, such as N,N'-bis(3,5-di-tert-butyl-4-hydroxy-hydrocinnamoyl)-hydrazine. The use of the alkylhydroxyphenylalkanoyl-hydrazine retains the inherent resistance to high voltage breakdown of the polyester resin component while not affecting the other properties of the composition, such as strength, modulus, shrinkage, etc.

Abstract: A complex of polyphenylene ether resin and methylene chloride obtained by polymerizing a phenol in methylene chloride and then cooling the mixture to cause the complex to precipitate, is mixed with a vinyl aromatic compound, e.g., styrene monomer, heated to decompose the complex and remove methylene chloride from the blend, and thereafter the vinyl aromatic compound is polymerized. The products are useful as molding resins and the like.

Abstract: A reservoir for holding and reprocessing foamy shed blood prior to reintroduction to a patient, the reservoir comprising a holding chamber divided by a filter into two sub-chambers, a foam killing chamber in open communication with one of the sub-chambers, and inlet and outlet ports for the blood. The apparatus removes cell debris and filterable products of hemolysis and avoids the need to return chemical foam killers and collapsed foam to the patient's body.

Abstract: This invention is for a process for the ortho-alkalation of phenols in the presence of a magnesium oxide alkylation catalyst. The process comprises the vapor phase reaction of a non-ortho-substituted phenol with an alcohol in the presence of an alkylation catalyst and is characterized by the introduction of water vapor into the reaction system. The water vapor effects continuous regeneration thereby substantially increasing catalyst life before regeneration is required. This is an important advantage as it increases the period of reactor operation before shut down is required, thereby making the overall process more economical.
