METHOD OF SYNTHESIS OF POLYETHYLENE OF SUPERHIGH MOLECULAR MASS Russian patent published in 1996 - IPC

FIELD: chemical technology, polymers. SUBSTANCE: product: polyethylene of superhigh molecular mass (1-6 mln). Method of synthesis involves ethylene polymerization under pressure 1-50 atm in the presence of catalyst consisting of microspherical titanium trichloride which is treated preliminary with higher alpha-olefin (hexene-1, octene-1, decene-1 or their mixture) in inert medium at amount 1 g/g titanium component and triethylaluminium (not less). Product is used for producing monolith half-finished articles by caking and pressing or by gel-spinning method. EFFECT: improved method of synthesis. 1 tbl
