Abstract:
A film-forming cosmetic composition useful as a facial pack, nail enamel, eye liner etc., which comprises a copolymer of vinyl alcohol and alkyl vinyl ether, being referred to simply as PVA/AVE, consisting of 98 to 80 mole% of vinyl alcohol monomer units and 2 to 20 mole% of linear or branched alkyl vinyl monomer units having from 1 to 6 carbon atoms.The molar ratio of the vinyl alcohol monomer units to the alkyl vinyl ether monomer units is in the range of from 95/5 to 85/15.The PVA/AVE according to the invention has no acetic groups with ester bonds in a molecule. Instead, there are alkyl or alkenyl groups having ether bonds which serve for steric hindrance for preventing gelation of an aqueous solution of such copolymer. From this reason, the PVA/AVE does not undergo any hydrolysis as time passes and is thus excellent in storage stability.

Abstract:
A process for the production of copolymers based on monomer(s) with a polyalkylene glycol group (I) and monomer(s) with a carboxylic acid group (II) involves copolymerisation in presence of a chelating agent (III) with a phosphonic acid group. An Independent claim is also included for copolymerisation products obtained by this process.
