<p><P>PROBLEM TO BE SOLVED: To improve the lowering of rigidity caused by the foreign materials of a reclaimed polyolefinic resin material obtained from its waste. <P>SOLUTION: The reclaimed polyolefinic material having a rigidity equal to or better than that of a fresh polyolefinic material is obtained by adding an auxiliary agent containing a resin modifier to a waste polyolefinic material. The resin modifier includes a crystalline olefin-ethylene-butylene-crystalline olefin block polymer (CEBC) and a maleic anhydride-modified polyolefinic resin or an olefinic graft copolymer, an olefinic elastomer and a maleic anhydride-modified polyolefinic resin. The resin modifier of≥0.5 pt.wt. is added to 100 pts.wt. of the waste polyolefinic resin. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
