POLYPROPYLENE FOR THE PRODUCTION OF THERMOFORMED ARTICLES, LARGE, DEEP, COMPLEX AND/OR THICK ARTICLES, PROCESS FOR THERMOFORMING MODIFIED POLYPROPYLENE INTO LARGE, DEEP, COMPLEX AND/OR THICK ARTICLES, AND USE OF THE POLYPROPYLENE |
摘要 |
The present invention is directed to a modified polypropylene comprising from 0.3 to 2 long-chain branches per 1,000 carbon atoms, wherein said long-chain branch has more than 1,000 carbon atoms and 0 to 6% of ethene and/or alpha-olefinic comonomer having 3 to 18 carbon atoms. The polypropylene of the present invention is a homopolymer, a random copolymer, or a heterophasic copolymer. The present invention also relates to large, deep, complex and/or thick articles which are thermoformed from said polypropylene. Furthermore, the present invention relates to the process for thermoforming said modified polypropylene into large, deep, complex and/or thick articles. The present invention also relates to the use of the polypropylene to prepare large, deep, complex and/or thick articles. |
