    Abstract: Polishing compsn based on an aq. dispersion of copolymers crosslinked with metal-ions, and which contains >=8 wt. % solids and has pH value 7-11, also contains oxidised polyethylene (O-content is not 2 wt. %) prepd by radical emulsion polymn, m.p. >100 degrees C, mol wt 7000-40000. Claimed polishes have improved solvent resistance; hence impart durable attractive gloss to floors thus treated even in places where presence of solvents tends to have a dulling effect on floor polishes (e.g. factories or offices where spray-cleaners are used).

    Abstract: Ethylene copolymer dispersions with a high solids content and a good freeze-thaw stability are prepd. by the aq. emulsion polymsn. of ethylene and an unsatd. comonomer contg. oxygen and/or sulphur in an amount giving a copolymer contg. 2.0 - 4.0 wt.% oxygen and/or 0.5 - 1.0 wt.% sulphur, in the presence of a free radial initiator, and of 2 - 20 wt.%, based on aqs. phase, of an emulsifier consisting of a mixt. of a 10 - 25C alkali metal alkylsulphonate and/or alkylsulphate, and a satd. or unsatd. fatty acid polyoxyethylate with 10 - 25C atoms in the carboxylic acid group, and 3 - 15 alkylene oxide units. The unsatd. comonomer is sodium vinylsulphonate. The emulsifier consists of a mixt. of a 13 - 17C alkali metal alkylsulphonate and an oleic acid oxyethylate with S ethylene oxide units.
