Abstract:
1. Plastics with high toughness, which comprise pseudoductile plastics with a macromolecular chain entanglement density (Ve) of greater than about 0.15 mmol/ml and a characteristic ratio (C ∞ ) of less than about 7.5; and rubber particles with an average particle size of 20 to 200 nm and a homogenous micro-structure, wherein the weight ratio of the rubber particles to the pseudoductile plastics is from 0.5:99.5 to 70:30; wherein the rubber particles are crosslinked rubber particles with a gel content of not less than 60 weight percent and are fully vulcanized powdery rubber selected from at least one of the following materials: fully vulcanized powdery natural rubber, fully vulcanized powdery butadiene-styrene rubber, fully vulcanized powdery carboxylic butadiene-styrene rubber, fully vulcanized powdery butadiene-acrylonitrile rubber, fully vulcanized powdery carboxylic butadiene-acrylonitrile rubber, fully vulcanized powdery chlorobutadiene rubber, fully vulcanized powdery polybutadiene rubber, fully vulcanized powdery silicone rubber and fully vulcanized powdery acrylate rubber.
