Abstract: Polyethylenes are produced continuously from a mixture of 100 wt. parts ethylene, 0.5-1.5 ppm (based on ethylene) of a radical polymersn initiator, and 0.05-5 wt. parts of a polymerisn. regulator, at increased temp. and press of 1000-3000 atm., in a tubular reactor having length, diameter ratio of 5000:1-30000:1. The polymerisn, mixture in introduced at 70-120 degrees C and the temp. increases to 230-280 degrees C in the first 5/15 of the tube, is maintained within 5 degrees C of this temp. in the next 9/15 of the tube, and is cooled in the last 1/15 to 30-60 degrees C. The mixture is passed through at 3-30 m/sec. Polymer produced has narrow softening range and also shows good mechanical properties outside this range.
