ABSTRACT
At equal conditions of polymerization [Ti : AI : piperylene = 1 : 1 ,25 : 2 mole (piperylene was introduced as modifier into catalytic complex solution at the moment of its preliminary ageing), ageing of catalytic system for 30 min at 273K, polymerization temperature 298K, toluene as a solvent, CT; = 6 mmole/1, Cl\1 = 1,5 mole/!] way of process carrying out was changed. Namely: Variant 1. Preliminary aged catalytic complex (two-component TiC14-Al(i-C4H9) 3 and ternary TiCI4-
Al(i-C4Hg)3-piperylene) and solvent from reservoirs 1 and 2 (Fig. 2.1) accordingly were mixed in tubular turbulent apparatus 3 at linear rate of flows in broad part (divergent) not less than 0,5 rn/sec and reagents residence time in mixing zone nearly 2-3 sec (hydrodynamic effect on catalytic system in turbulent regime). From apparatus 3 catalyst solution entered into vessel 4 where isoprene was added. Then polymerization was carried out at slow mixing.
