标 题:Method for the production of an article from the Copolymer of Lactide and (e)-Caprolactone for medical applications
发明人：GRIJPMA DIRK WYBE; PENNINGS ALBERT JOHAN
权利人:UNIV GRONINGEN
摘要:The invention relates to a method for the production of an article from a copolymer of lactide and epsilon -caprolactone for medical applications, in which method the copolymer is obtained by a synthesis which is carried out as a bulk synthesis at a temperature of 80 to 160 DEG C. Articles according to the invention can be used in numerous fields, but are in particular advantageous if they are employed in biomedical fields. Examples are an implant for the repair of a meniscus or a blood vessel, stents or artificial skin. Stents are small spirals which are used to hold open (coronary) arteries which have silted up. Use in abdominal wall reconstruction is also possible.

标 题 :Phosoxophite ligands and use thereof in carbonylation processes
发明人：PENG WEI-JUN; BRYANT DAVID ROBERT
权利人:UNION CARBIDE CHEM PLASTIC
摘要:A novel organophosphorus composition and synthesis thereof, the composition being characterized by one phosphite moiety, one phosoxophite moiety, and a plurality of sterically bulky substituents. The novel composition finds utility as a ligand in Group VIII transition metal phosoxophite complex catalysts and complex catalyst precursors that are used in carbonylation processes, preferably, hydroformylation processes. Additionally, there is disclosed a novel method of preparing a phosphoromonochloridite composition that finds utility as a precursor to the novel phosoxophite composition.
