摘要： Disclosed are novel compositions comprising blends of at least about 75 percent by weight of a polyesteramide and the balance of the blends comprising a urethane containing ingredient. Optionally, an antioxidant component is present in the blends.The blends display an unexpected level of stability in regard to their tensile properties when exposed to elevated temperatures.The blends find particular utility in the area of hoses, gaskets, seals, etc., used in handling fluids at elevated temperatures.

摘要： Substantially linear, segmented polyester amides are described which contain aromatic residues in the "hard" segments but which still possess sufficiently low melt properties to be injection moldable. The polyester amides are obtained by reacting a carboxylic acid-terminated prepolymer (derived by reacting an excess of a dicarboxylic acid with a polymeric diol of molecular weight 400 to 4000) with a stoichiometric amount of methylenebis(phenyl isocyanate) or toluene diisocyanate or mixtures of these isocyanates and, optionally, a dicarboxylic acid.

摘要： Segmented thermoplastic polyester-amides are described which are prepared by reacting a polymeric diol (molecular weight in the range of 400 to 4000) with a carboxylic acid terminated prepolymer obtained by reacting an aliphatic ether diamine, optionally in admixture with a minor proportion (based on equivalents) of an alkylene diamine, with an excess of dicarboxylic acid (aromatic or aliphatic). The polyester-amides, which can be prepared preferably by the melt condensation method, have excellent physical properties and resistance to degradation by heat.

摘要： Disclosed are homogeneous blends comprising (a) a poly(alkylene terephthalate) and (b) a sufficient amount of a crystalline polyamide to impart enhanced crystallization velocity to said polyalkylene terephthalate. The crystalline polyamide comprises a narrow class of aromatic-aliphatic polyamides prepared from 4,4'-methylenebis(phenyl isocyanate) and a small group of aliphatic dicarboxylic acids.the poly(alkylene terephthalates) are characterized by enhanced crystallization rates which lead to a number of improved properties over the base polyester.
