Abstract
A new ethylene copolymer comprising: a repeating unit (A) represented by the formula: EQU --CH.sub.2 --CH.sub.2 --; a repeating unit (B) represented by the formula: ##STR1## (wherein R.sup.1 is defined as hereinbefore), and a repeating unit (C) represented by the formula: ##STR2## (wherein R.sup.2 and R.sup.3 are defined as hereinbefore), said repeating units (A), (B) and (C) being orientated in a random and straight chain arrangement, said repeating unit (B) content being 0 to 45 mol %, said repeating unit (C) content being 0.001 to 45 mol %, and said copolymer having a weight average molecular weight of at least 5,000. A process for producing said ethylene copolymer by using a catalyst containing a specific chromium compound.
