  • Toughened plastics and its preparation method
    Patent number: 9181419
    Abstract: A toughened plastic and its preparation method, with the toughened plastic being obtained by rubber-plastic blending of brittle or less brittle plastics and a rubber mixture. The rubber mixture consists of powdery rubbers having a cross-linked structure and an average particle size of not more than 0.50 ?m, and at least one selected from the group consisting of unvulcanized rubbers and thermoplastic elastomers. The morphology and the particle size distribution of the rubber phase contained in the toughened plastic can be controlled by changing the particle size of the powdery rubbers having a cross-linking structure and choosing proper unvulcanized rubbers or thermoplastic elastomers. The toughened plastic has good toughness and processability while keeping better strength and stiffness.

  • Toughened plastics and its preparation method
    Publication number: 20040077792
    Abstract: The present invention provides a toughened plastic and its preparation method, with said toughened plastic being obtained by rubber-plastic blending of brittle or less brittle plastics and a rubber mixture. Said rubber mixture consists of powdery rubbers having a cross-linked structure and an average particle size of not more than 0.50 &mgr;m, and at least one selected from the group consisting of unvulcanized rubbers and thermoplastic elastomers. The morphology and the particle size distribution of the rubber phase contained in said toughened plastic can be controlled by changing the particle size of the powdery rubbers having a cross-linking structure and choosing proper unvulcanized rubbers or thermoplastic elastomers. The toughened plastic, according to the present invention has good toughness and processability while keeping better strength and stiffness.
