Abstract: PROBLEM TO BE SOLVED: To obtain the subject polyurethane excellent in reactivity and mechanical characteristics, by reacting an isocyanate with a polyol containing a polyether polyalcohol having a specific structural unit, molecular weight and degree of unsaturation. SOLUTION: This polyurethane is obtained by reacting an isocyanate with,2 polyol having a molecular weight of 500-1000, including at least one kind of polyether polyol (preferably, including 5-30 wt.% ethylene group, based on the total weight of all polyoxyalkylene groups and having a hydroxyl number of 10-230 mgKOH/mol and functionality of 1.9-3.0) having a molecular weight of 500-10000 g/mol, degree of unsaturation of

Abstract: PROBLEM TO BE SOLVED: To obtain an excellent abrasion resistance by compounding, at a specific wt. ratio, a thermoplastic polyurethane having a specific Shore hardness as well as an ethylene/propylene rubber, a modified ethylene/propylene rubber or a mixture thereof. SOLUTION: This is a compsn. comprising a thermoplastic polyurethane (A) having a Shore hardness of from 60A to 50D as well as an ethylene/ propylene rubber, a modified ethylene/propylene rubber or a mixture thereof (B), at the wt. ratio A/B=3/1-999/1. It also comprises optionally a plasticizer, a light stabilizer, a lubricant, a binding agent, a filler and a reinforcing agent. The ethylene/propylene rubber for use has a Mooney viscosity: L(1+4) (100 deg.C) of 35 or more and an MF1 (230 deg.C and 10 kgs) of 8 or more. The modified ethylene/propylene rubber is grafted with a reactive carboxylic acid or its deriv. such as (meth)acrylic acid, glycidyl (meth)acrylate or maleic anhydride.
