Experimental data on the specific volume of a 50% crystalline sample of poly(tetrafluorethy1ene) are presented and discussed. Data points were taken along 22 isotherms spaced 5 to 3OoC apart (up to 372OC) in pressure increments of 100 kghm2 up to ZOO0 kg/cm2. In addition to the melting transition an
The pressure-volume-temperature (P-V-T) properties of a number of metallocene-produced polyolefins were measured experimentally at 10 MPa Υ P Υ 200 MPa and 30Β°C Υ T Υ 220Β°C in a dilatometer-type P-V-T apparatus. These included ethylene copolymers typical of linear low density polyethylene, with seve
