VERFAHREN ZUR HERSTELLUNG VON DURCH MALEINSÄUREANHYDRID MODIFIZIERTEN POLYPROPYLENEN |
摘要 |
The invention relates to a method for producing polypropylenes modified by maleic acid. According to said method, which has a functionalisation degree of between 0.1 and 5 wt. %, particle-shaped propylene homopolymers are used, as well as statistic (random) or heterophasic propylene copolymers as a polymer skeleton and organic peroxides are used as radical formers by means of solid phase grafting of maleic acid anhydride (MSA), optionally MSA in a mixture with a comonomer from the series of vinylaromatics or (meth) acrylic acid esters, by maintaining a dry-fluid phase at reaction temperatures of between 125 and 160 DEG C. Said maleinated polypropylenes can be used as phase mediators in polymer blends or as reactive couplers in polymer composites and as adhesive coating materials for different surfaces. |
