METHOD OF TREATING INOCULATING LAYER BEFORE POLYMERISATION REACTION Russian patent published in 2011 - IPC C08F10/00 C08F2/34 

Abstract RU 2424251 C2

FIELD: chemistry.

SUBSTANCE: method involves preparation of a reactor to a polymerisation reaction, wherein said method comprises the following steps: (a) loading an inoculation layer into the reactor, (b) preliminary loading of at least one homogeneity additive, where the homogeneity additive contains a metal stearate or salt which is a metal carboxylate, and (c) carrying out a polymerisation reaction in the reactor after steps (a) and (b), including at least the initial step of the reaction in the presence of the homogeneity additive. The invention also discloses olefin polymerisation methods.

EFFECT: invention prevents stratification or formation of a precipitate during the initial polymerisation step.
