    Abstract: A propylene (co) polymer terminated with a reactive group and a process for the preparation of the same. A graft copolymer having a specific side chain and a process for the preparation of the same. The propylene (co) polymer is usable as a radial- or ion-polymerizable propylene macromonomer or as an intermediate for the preparation of a block polymer. Examples of the application thereof include compatibizing agent for polymers, light- or laser-curable plastic, viscosity index and surface modifier. The graft copolymer is useful as a surface modifier or compatibilizing agent for polypropylene or a dispersant for fillers.

    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.
