Beschreibung
Zusammenfassung:	chemistry of polymers. SUBSTANCE: described are polyethylenes having narrow molecular weight distribution and narrow composition distribution. Ethylene polymer has polydispersity index of about to 4, distribution index from about 1.0 to 9 along length of crystallizable chains LW/LN and turbidity index of less than 370 p- 330 in which p is density in manufacturing films, index of ethylene polymer relaxation time spectrum and melt index for said polymer having the following relationship: about 2,5 < (¤Ð‰ð)(’ð016)] < about 6,5, wherein MI is index of ethylene polymer relaxation time spectrum and IEPR is melt index. Ethylene polymer have preferably combination of high transparency and shock resistance with low content of extractable agent and improved processibility in manufacturing products such as film. EFFECT: improved properties of the title products. 8 cl, 1 tbl
