PURPOSE:To provide the title compsn. having a high crystallization temp. and excellent flexural modulus, etc., containing a polymer obtd. by hydrogenating a radical or anionic polymer of a styrene derivative. CONSTITUTION:A radical or anionic polymer having a number-average MW of not lower than 3,000, obtd. by polymerizing a styrene derivative of the formula (wherein R1 is H or an alkyl; R2 is R1, an aryl or halogen) in the presence of a radical polymn. catalyst (e.g., an azo compd.) or an anionic polymn. catalyst (e.g., an alkyl compd. of Ca, K, etc.) is hydrogenated to obtain a hydrogenated polymer (B) of a styrene derivative polymer. A crystalline PP (A) is melt- kneaded with 0.05-10,000wt.ppm of the component B and optionally, a thermal stabilizer, a light stabilizer, an antistatic agent, an antioxidant, a pigment, a flame retarder, etc. |
