    Abstract: Uniformly sized, fine particles of a polymer is produced by: (1) mixing (B) a nonionic organic compound being liquid at room temperature, having a solubility in water at 25 DEG C of 0.01 wt.% or larger and being compatible with (A) an oil-soluble, ethylenically unsaturated monomer, with the monomer (A) in an amount of 0.5 to 300 wt.% based on the monomer (A), (2) then adding the mixture of (A) and (B) to an aqueous dispersion of (C) particles of a seed polymer so as to make the mixture of (A) and (B) absorb onto the paricles (C) and (3) polymerizing the mixture of (A), (B) and (C) in the presence of an oil-soluble initiator for the polymerization to obtain said uniformly sized, fine particles.

    Abstract: A metal working water-soluble lubricant composition comprising a water-soluble polymer compound whose counter anion is acidic phosphorus-containing compound or boric acid is disclosed. The water-soluble polymer compound is selected from the group consisting of cationic or amphoteric addition polymers, ring-opened polymers, polycondensation products and salts or quaternary ammonium salts of natural polymer derivatives having at least one basic or cationic nitrogen atom in one molecule thereof with a molecular weight of 1,000 to 10,000,000. The composition has a load resistance equal to or higher than known liquid lubricants which contain mineral oils, beef tallow etc., and shows an excellent lubricating performance when applied to a metal working surface.

    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: New water-soluble bis(2-glucosamidoalkyl)disulphides, represented by the following formula I: in which n is an integer ranging from 1 to 3, are prepared by reacting delta -gluconolactone and a bis(aminoalkyl)disulphide, or by reacting delta -gluconolactone and an aminoalkanethiol, in order to obtain an N-mercaptoalkylglucosamide, followed by oxidation with known oxidising agents. The bis(2-glucosamidoalkyl)disulphides thus obtained are soluble in water and are odourless and, as a result, they can be used as antioxidants or as regulating agents in polymerisation involving free radicals.
