Abstract: A polymeric blend contains a polyether block amide and a thermoplastic polymer, where the polyether block amide is based on a subunit 1 and a subunit 2. Subunit 1 is composed of at least one linear aliphatic diamine containing 5 to 15 carbon atoms and at least one linear aliphatic dicarboxylic acid containing 6 to 16 carbon atoms. Subunit 2 is composed of at least one polyether diol containing at least 3 carbon atoms per ether oxygen and primary OH groups at the chain ends. The sum total of the carbon atoms from diamine and dicarboxylic acid is an odd number and is 19 or 21 carbon atoms. The number-average molar mass of the subunit 2 is 200 to 900 g/mol. The thermoplastic polymer is selected from an ethylene/vinylene acetate, a thermoplastic polyester elastomer, a polyolefin elastomer, thermoplastic polyurethane, or any mixture thereof.

Abstract: The present invention relates to the field of manufacture of polymer materials, and more particularly to an ultra-high molecular weight polyethylene (UHMWPE) composition and a cut resistant and creep resistant fiber prepared therefrom. The ultra-high molecular weight polyethylene composition comprises the following components: modified graphene, modified silicon carbide whisker, and ultra-high molecular weight polyethylene. The ultra-high molecular weight polyethylene composition provided by the present invention has superior cut resistance, high strength and high modulus. By regulating the morphology of silicon carbide, the type of a coupling agent, the mixing ratio and so on, not only cut resistance, high strength and high modulus can be provided, but also creep resistance can be improved.
