PROPYLENE/ETHYLENE RANDOM COPOLYMER, MOLDING MATERIAL, AND MOLDED ARTICLE |
摘要 |
<p>The present invention provides propylene/ethylene random copolymers characterized in that: an ethylene content (Ew) is 0.1-10 wt%, a relationship between an isolated ethylene content (E1) and the ethylene content (Ew) is represented by the following equation <MATH> 2,1- and 1,3-propylene units present in a polymer chain are 0-1 mol%, a weight average molecular weight (Mw) is in the range of 40,000-1,000,000, and a ratio (Mw/Mn) of the weight average molecular weight (Mw) to a number average molecular weight(Mn) is in the range of 1.5-3.8. The copolymers are suitable for a base resin for a molding material for the production of a wide variety of molded articles which are high in randomness and excellent in stiffness, heat resistance and transparency. <IMAGE></p> |
