A halogenated product of a low-molecular weight ethylene random copolymer comprising ethylene and at least one alpha-olefin having 3 to 20 carbon atoms, wherein: (i) the starting low-molecular weight ethylene random copolymer contains 30% to 75% by mole of the ethylene component and 25% to 70% by mole of the alpha-olefin component; (ii) the halogen content of the halogenated product is 5% to 75% by weight; (iii) the intrinsic viscosity [ eta ] of the halogenated product is 0.01 to 0.5 dl/g determined at 135 DEG C. in decalin; (iv) the molecular weight distribution &upbar& Mw/ &upbar& Mn of the halogenated product, wherein &upbar& Mw and &upbar& Mn represent a weight-average molecular weight and a number-average molecular weight, respectively, determined by gel permeation chromatography is 5 or less; and (v) the number-average molecular weight of the halogenated product is 300 to 1000, determined by gel permeation chromatography. This halogenated ethylene random copolymer has an excellent solubility in solvents and excellent compatibility to various kinds of resins and lubricating oils. Especially, the halogenated ethylene random copolymer is suitable for use as a modifier for halogen-containing polymer such as polyvinyl chloride and polyvinylidene chloride, a compounding agent for, for example, a lubricating oil, a paint composition, an ink composition, an adhesive, a tackifier, and a thickening agent, and a flame retardant.
