HYDROGENATED BLOCK COPOLYMER AND POLYPROPYLENE RESIN COMPOSITION CONTAINING THE SAME |
摘要 |
A hydrogenated block copolymer which is made up of two polymer blocks A derived from a vinylaromatic hydrocarbon compound and one hydrogenated butadiene polymer block B in which at least 90 % of the olefinic double bonds have been hydrogenated, wherein the content of the vinylaromatic hydrocarbon compound units in the copolymer is higher than 13 wt.% but lower than 25 wt.%, the content of 1,2-bonds in the butadiene polymer block before hydrogenation was higher than 40 mol % but lower than 60 mol %, and the copolymer has a quantity of heat of crystal fusion smaller than 0.05 J/g, an order-disorder transition temperature of 200 DEG C or higher, and a melt flow rate of 0.1 to 30 g/10 min, excluding 30 g/10 min.
