• Graft copolymers and blends thereof with polyolefins

  公开（公告）日：1989-10-04

  A novel graft copolymer capable of imparting to a polyolefin when blended therewith a good balance of tensile modulus, sag resistance and melt viscosity, is a polyolefin trunk having a, preferably relatively high weight-average molecular weight, methacrylate polymer chain grafted thereto. The graft copolymer is formed by dissolving a non-polar polyolefin in an inert hydrocarbon solvent, and, while stirring the mixture, adding methacrylate monomer together with initiator to produce a constant, low concentration of radicals, and covalently graft a polymer chain, preferably of relatively high molecular weight, to the polyolefin backbone. The graft copolymer can be separated from the solvent, by volatilizing the solvent, for example in a devolatilizing extruder, and pelletised or extruded or otherwise shaped into a desired shape such as a sheet, tube or the like. This graft copolymer can be blended with a polyolefin matrix to improve its physical properties in the melt, upon cooling, and in the solid state, and is useful in cast and oriented films, solid extruded rod and profile, foamed rod, profile and sheet and blown bottles. The graft copolymer can also be used to improve compatibility between polymers in a wide range of polymer blends.

  一种新型接枝共聚物是一种聚烯烃主链，其上接枝了甲基丙烯酸酯聚合物链（最好是相对较高的重量平均分子量），当与聚烯烃混合时，可赋予聚烯烃拉伸模量、抗下垂性和熔体粘度良好的平衡。接枝共聚物的形成方法是：将非极性聚烯烃溶解在惰性烃类溶剂中，然后在搅拌混合物的同时，加入甲基丙烯酸酯单体和引发剂，以产生恒定的低浓度自由基，并将聚合物链（最好是相对高分子量的聚合物链）共价接枝到聚烯烃主干上。接枝共聚物可以通过挥发溶剂（例如在脱溶剂挤出机中）与溶剂分离，然后造粒或挤出或以其他方式制成所需的形状，如片状、管状或类似形状。这种接枝共聚物可与聚烯烃基体混合，以改善其在熔融、冷却和固态时的物理性能，适用于流延膜和拉伸膜、固体挤压棒材和型材、发泡棒材、型材和片材以及吹瓶。接枝共聚物还可用于改善各种聚合物混合物中聚合物之间的相容性。
