Patent number: 5541244Abstract: The invention relates to polymer mixtures comprising a first polyalkylene phthalate and a second polyalkylene phthalate and/or a thermoplastic elastomer. Certain compounds, namely phosphates, have been found to be good transesterification inhibitors. An important advantage of the said inhibitors is that they do not condense, or hardly condense, to polyphosphates and that they do not negatively influence the impact strength of the polymer mixture.Type: GrantFiled: October 10, 1995Date of Patent: July 30, 1996Assignee: General Electric CompanyInventors: Roelof van der Meer, Constantinus L.

Patent number: 5500212Abstract: New bile acid sequestrant polymer compositions and a process for preparing the polymers in particulate form, preferably in spherical form, are described. The polymer particles are prepared by crosslinking an amine-containing polymer with an amount of a polyfunctional amine-reactive compound sufficient to crosslink the polymer so that it is essentially water insoluble and has bile acid sequestering efficacy greater than that of cholestyramine, preferably greater than about three times the efficacy of cholestyramine. A preferred polymerization process revolves suspension polymerization of water-soluble amine-containing monomers, such as dialkylaminoalkyl (meth)acrylate esters and dialkylaminoalkyl (meth)acrylamides, in the presence of polyfunctional amine-reactive compounds, such as substituted dihaloalkanes. Pharmaceutical compositions containing the bile acid sequestrant polymer particles and a method for lowering blood cholesterol levels using the pharmaceutical compositions are also described.Type: GrantFiled: June 6, 1995Date of Patent: March 19, 1996Assignee: Rohm and Haas CompanyInventors: Paul E.
