Patent attributes
Disclosed is a segmented thermoplastic elastomer that can be a polyurethane, polyurea, or polyurethane-urea comprising soft segments and hard segments, wherein the soft segments are made of polyolefin diols or polyolefin diamine that may have 0 to 1000 carbon atoms in the main chain, wherein each carbon atom in the main chain may have 0 to 2 side chains and each side chain may have 0 to 30 carbon atoms, the hard segment is made of a diisocyante and a chain extender, the hard segments make up 10-60% of the elastomer and the soft segments make up the rest, the number-average molecular weight of the elastomer is 5×103-1000×103 g/mol, the ultimate elongation of the elastomer is 100-1000%, the Young's modulus is 1 to 3,000 MPa, and the ultimate tensile strength is 10-100 MPa. Also disclosed are a method for preparing the segmented thermoplastic elastomer and use of segmented thermoplastic elastomer.
