PRODUCTS OF OLIGOMERIZATION OF 10-PROPENYL PHENOTHIAZINE AS STABILIZING AGENT FOR POLYOLEFINS Russian patent published in 1997 - IPC

Abstract RU 2100360 C1

FIELD: production of stabilized polymer compositions. SUBSTANCE: products of oligomerization of 10-propenyl phenothiazine having common formula $$$ where n=1,2; m=1 are prepared by polymerization of origin monomer. The process is carried out at 20-25 C in organic solvent in the presence of catalyst, its quantity is (3-6)$$$ moles per 1 mole of origin monomer. Etherate of boron trifluoride is used as catalyst. EFFECT: higher efficiency. 4 tbl
