GAS-PHASE POLYMERIZATION METHOD

摘要

FIELD: polymerization processes. SUBSTANCE: method ensures introduction of polymerization catalytic system without carrier into gas-phase reactor, where said system contains (i)polymerization catalyst-containing nonvolatile fraction; (ii) solvent fraction which at least partly mixes with nonvolatile fraction and is sufficiently volatile to provide formation of polymerization catalyst particles when mixture of solvent fraction and nonvolatile fraction is pulverized in reactor; (iii) compressed liquid; and (iv), optionally, slowly vaporizing solvent. EFFECT: simplified process. 17 cl, 3 ex
