Abstract: Ultra high molecular weight polystyrene with Mw=68.3 × 104-266 × 104, D=2.9-7.2 was synthesized.The electrical, thermal, mechanical characters and rheologic behaviour were determined.The impact strength of the products was found to be 17.9-38.4 J/m, bending strength 86.8-110.5 MPa, hot resistance 93-98℃, transparency 89% and flowviscosity activation energy 67.7 kJ/mol.
