PURPOSE:To obtain a stable polybutene emulsion having low molecular weight and suitable as a wax diluent, cleaning solvent, etc., by compounding a (hydrogenated) polybutene having a specific molecular weight with two specific kinds of emulsifiers such as polyoxyethylene alkyl(alkenyl) ether. CONSTITUTION:The objective polybutene emulsion composed of 1-75wt.% of solid component of the emulsion and the remaining part of water is produced by compounding (A) 100 pts.wt. of a polybutene and/or hydrogenated polybutene having an average molecular weight of 300-500 with (B) 3-20 pts.wt., preferably 5-15 pts.wt. of a polyoxyethylene alkyl(alkenyl) ether of formula (R is alkyl or alkenyl; n is integer other than 0, preferably 1-20) and (C) 0.1-10 pts.wt., preferably 1-5 pts.wt. of a sorbitan fatty acid ester. |
