The invention relates to semi-finished products or moulded materials of improved toughness made from propylene polymers and from polymeric C8-C14-vinylaromatics and/or polymethyl methacrylate in the form of embedded nanoparticles. The semi-finished products or moulded materials can be produced by sorption of mixtures made from C8-C14-vinylaromatics and/or methyl methacrylate with thermally decomposing free-radical generators by semi-finished products, moulded materials or pellets made from propylene polymers, and then polymerization of the absorbed monomers present in the semi-finished products, moulded materials or pellets made from propylene polymers, where appropriate with processing of the modified pellets to give semi-finished products or moulded materials.
The semi-finished products or moulded materials are suitable for use as highly stressed components in the sectors of vehicle construction, household devices, mechanical engineering, electrical devices or electronics.
本发明涉及由丙烯聚合物和嵌入纳米颗粒形式的聚合 C8-C14-乙烯基芳烃和/或聚 甲基丙烯酸甲酯制成的韧性更好的半成品或模塑材料。半成品或模塑材料可通过丙烯聚合物制成的半成品、模塑材料或颗粒吸附由 C8-C14-vinylaromatics 和/或甲基丙烯酸甲酯与热分解自由基发生器制成的混合物,然后聚合存在于丙烯聚合物制成的半成品、模塑材料或颗粒中的被吸收单体,在适当的情况下,对改性颗粒进行加工,得到半成品或模塑材料。
这些半成品或模塑材料适用于车辆制造、家用设备、机械工程、电气设备或电子产品等领域的高强度部件。
