Method of producing superhigh-molecular weight polyethylene |
| abstract |
FIELD: polymer production. n SUBSTANCE: superhigh-molecular weight polyethylene is obtained in suspension conditions at temperature between 40 and less than 70°C in hydrocarbon solvent medium using supported catalyst. The latter is prepared through interaction of compound Mg(C 6 H 5 )2 n *MgCl 2 *mR 2 O (R 2 O is ether, R = i-Am, n-Bu) with silicon compound, which is a product prepared by reaction of compound R 1 kSiCl 4-k with silicon tetraethoxide Si(OR) 4 (R 1 represents methyl or phenyl and k=0.1) at molar ratio R 1 kSiCl 4-k /Si(OR)4 = 2-4 at 15-45°C and Si/Mg = 1-2.5. Loose weight of obtained polymer is higher than 0.35 g/cc. n EFFECT: increased yield of superhigh-molecular weight polyethylene with improved morphology. n 1 tbl, 13 ex |
