摘要： Disclosed are injection moldable, rapidly crystallizable compositions comprising (A) a linear polyamide selected from the series poly(4,4'-methylenediphenylene azelamide to dodecanediamide); and (B) an amount sufficient to promote the crystallization of the linear polyamide, of a material selected from the group of (i) talc, (ii) sodium benzenesulfonate, (iii) a polyethylene ionomer, (iv) a methacrylated butadiene-styrene, and (v) a multi-phase composite interpolymer.The compositions crystallize rapidly from the molten state which allows for economically attractive molding procedures including fiber production and the production of aromatic-aliphatic polyamides having a combination of excellent properties.

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.

摘要： Novel polyamide block copolymers are provided which comprise a central block of a soft segment derived from the residue of a polymeric polyol or polycarboxylic acid joined to terminal hard segment polyamide blocks. The linkages which join the blocks are of a novel type and are the opened form of certain monoazetidine-2,4-dione rings.The block copolymers can be prepared very rapidly via anionically polymerizing lactams on to prepolymer soft segments containing terminal azetidine-2,4-dione rings.The speed with which the polymerizations can be carried out make the block copolymers particularly useful for the RIM preparation of molded parts.

摘要： Polyurethane resins are described having high impact strength and other structural strength properties, and significantly improved resistance to deformation by heat. The properties of these materials are such as to make them comparable to engineering thermoplastics such as nylon and like materials commonly used to fabricate structural components such as automotive parts, equipment housing, sporting goods, furniture, toys, household and like consumer goods.The resins are prepared from organic polyisocyanates, an isocyanate-reactive material (polyol, polyamine, etc.) having an average functionality of at least 1.9, a Tg less than 20.degree. C. and molecular weight of 500-20,000, and one or more low molecular weight extenders the major distinguishing feature being the markedly lower proportion by weight (2 to 25 percent) in which the isocyanate-reactive material is employed as compared with polyurethane resins conventionally prepared in the art. Depending upon the particular combination of reactants employed the polyurethanes of the invention can be thermoplastic or thermoset and can be prepared in both cellular and non-cellular form.

摘要： Disclosed are novel blends comprising segmented polyesteramides with minor amounts of carbodiimide containing materials.The blends are characterized by excellent physical properties and improved compression set characteristics over the polyesteramides in the absence of the carbodiimide component. This allows the polymers obtained to find utility in the making of seals or gaskets which heretofore the base polyesteramides could not satisfy.
