性が不良であることが欠点の一つとなっている。Propylene polymer is easy to obtain and has physical properties that meet market requirements to some extent, so it is used in various fields as a general-purpose resin, but it has poor paintability because its molecular structure has no polarity. This is one of the drawbacks.
この欠点を解消するために、エラス）ｗ−を添加する方

ーを添加する方法が行なわれている。In order to overcome this drawback, a method of adding elas) w- is known, but there is a problem with compatibility with the propylene polymer and the rigidity decreases, so a method of further adding an inorganic filler is known. is being carried out.
しかし、エラストマーおよびフィラーを多ｔＫ配合する
ことは、プロピレン重合体の持つ低密度、光沢、肌触り
感を損ねることになり好ましくない。However, blending an elastomer and a filler with a high tK is not preferable because it impairs the low density, gloss, and texture of the propylene polymer.

ック共重合体（ＥＰＰ）には効果が低い。Also known is a method of blending propylene polymer with ethylene-propylene copolymer rubber (KPM) or ethylene-propylene-nonconjugated diene terpolymer rubber (EPDM); Although it is effective for copolymer (PP), it is less effective for ethylene-propylene block copolymer (EPP).

ン重合体組成物に存する。The present invention solves these drawbacks, and by blending a small amount of styrene-isoprene block copolymer, the paintability of propylene polymer can be improved, and it can meet the increasingly sophisticated performance demands from the market. The purpose is to provide a propylene polymer composition that has paintability and is sufficiently effective without surface treatment of molded products. The present invention provides a propylene polymer composition with improved paintability, characterized in that a copolymer is blended in a proportion of W to 100% by weight based on the total of both components.
