    摘要: Condensation polymers of high molecular weight, such as polyesters, polyureas, and polyamides, are usually prepared at temperatures of 200.degree. C. or greater. However, by utilizing the catalyst systems of the present invention, condensation polymers can be synthesized at much lower temperatures. The polycondensation catalyst systems of the present invention are particularly useful for synthesizing aliphatic polyesters, such as polyethylene terephthalate, from dicarboxylic acids and aliphatic glycols. The present invention more specifically discloses a process for the synthesis of an aliphatic polyester comprising polymerizing at least one dicarboxylic acid with at least one aliphatic glycol in the presence of (1) at least one phosphorus containing compound which contains at least one trivalent or pentavalent phosphorus atom which is bonded directly to at least one phenyl group, (2) an acid acceptor, and (3) at least one halogenated organic compound. It is preferred to utilize a polymeric agent having bound acid acceptor groups as the acid acceptor in the process of the present invention.

    摘要: Antithrombogenic synthetic elastomer having repeat units comprising portion I which is a soft segment unit containing a polyether and portion II which is a hard segment unit: ##STR1## R is a straight-chain or branched-chain alkylene group containing 2 to 4 carbon atoms, R' is amide a urethane, an urea, n ranges up to 180, m is an integer of 1 to 20, l is an integer of 1 to 10, said polymer having a microdomain structure composed of soft and hard segments, the domains of which have an average size of 10 to 20 nm, and a molecular weight of about 80,000 to about 500,000.The polymer shows little adhesion of blood platelets thereto, little deformation of adhering blood platelets and an excellent antithrombogenic property. This polymer has excellent mechanical properties as an elastomer. This polymer is useful for artificial organs such as blood vessels, kidneys, hearts, and for functional biomaterials and devices such as absorbents for biological components, carriers for sustained release preparations, adhesive materials for living tissue, injectors, blood bags and catheters.

    摘要: Described herein is a novel process to resolve a racemic compound into its optically active isomers without need for chemical transformation such as salt formation. The process advantageously utilizes polymers containing chiral moieties in their repeat units as well as exhibiting critical solution temperature behavior in a suitable solvent. An embodiment describes the resolution of tryptophan.
