Abstract

Emulsifiable ethylene polymers comprising copolymers offrom 90 to 95% by weight of ethylene,from 4 to 10% by weight of one or more C3-C12 alkenecarboxylic acids, andfrom 0 to 1.2% by weight of one or more tertiary esters of the corresponding C3-C12 alkenecarboxylic acids,where the wax has a cinematic melt viscosity of from 800 to 3000 mm2/s, measured at 120° C.;and a process for preparing the novel emulsifiable ethylene polymers, emulsions comprising the novel ethylene polymers, a process for preparing the emulsions from the novel ethylene polymers, and also floor cleaners, car cleaners, leather cleaners and stone cleaners, and coatings for surfaces made from wood, metal, paper, glass or from plastics, comprising aqueous emulsions of the novel emulsifable waxes.
