A process for producing a polyester container having a higher strength than usual and a reduced wall thickness, whereby the polyester is present in a reduced amount contributing to resource savings, which includes preparing a polyester resin composition containing a polyester resin and 0.1 to 10 parts by weight, based on 100 parts by weight of the polyester resin, of an additive compound selected from the group consisting of compounds represented by the formula (I): ##STR1## and compounds represented by the following formula (II): ##STR2## and subjecting the resin composition to stretch blow molding.

Polyester container and process for producing the same

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.

Propylene (co)polymer and process for the preparation of the same

A cosmetic agent serves to form film being durable to various effects and comprises a copolymer of a fluoroalkyl (meth)acrylate and a long chain, linear alkyl (meth)acrylate. It may further comprise a volatile oil and solid fat(s).

Cosmetic comprising fluoroalkyl (meth)acrylate copolymers

An electrophotographic toner composition, improved in uniform dispersion therein of carbon black and electrophotographic properties, comprises a binder polymer, carbon black and a compound selected from the group consisting of a sulfonate compound having the formula (I), an alkaline earth metal salt of a basic alkylphenol persulfide having the formula (II), an alkyl or alkenyl succinic acid imide having the formula (III-1) or (III-2), an alkyl salicylic acid salt having the formula (IV), a compound having the formula (V) and a product obtained by treating the compound (V) with sulfur, in which R, R', R1 and R2 are a substituent and M is an alkaline earth metal. ##STR1##

Electrophotographic toner composition

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.
