| 发明名称 | Process for preparing high melt strength propylene polymers | ||
| 摘要 | A process for preparing high melt strength propylene polymers is provided. The process comprises: blending base propylene polymers with 0.1 to 1% w/w of polyfunctional acrylate monomer, in the presence of 10 to 50 ppm organic peroxide and 0.2 to 20% w/w of an additive such as stabilizer, acid neutralizer, antioxidants or lubricants. The high strength modified propylene polymers obtained have 30 to 60% of increased melt strength than that of the base propylene polymers. | ||

| 主权项 | 1. A process for preparing high melt strength propylene copolymers having melt strength 30% to 60% greater than that of a base propylene copolymer, said process comprising: reactive blending of the base propylene copolymer with 0.1 to 1% w/w of polyfunctional acrylate monomer, in the presence of 10 to 50 ppm organic peroxide and 0.2 to 20% w/w of at least one additive, said additive selected from the group consisting of stabilizers, acid neutralizers, antioxidants and lubricants. | ||
