摘要:
A process for producing copolymer latex by the emulsion polymerization of an aliphatic conjugated diene monomer and another monomer copolymerizable therewith in the presence of a cyclic unsaturated hydrocarbon having one unsaturated bond in the ring, characterized in that the addition of a monomer mixture containing the diene monomer is followed by the addition of another monomer mixture free from the diene monomer, or that part of a chain transfer agent is added after the addition of the monomers. The obtained latex is useful as an adhesive composition, paper coating composition, carpet backing adhesive composition, rock fiber base adhesive composition, gravure paper coating composition, color developing agent composition for pressure-sensitive paper, and the like.

A method for producing cardable, hydrophobic polyolefin-based staple fibres, comprising applying to spun filaments a first spin finish comprising an antistatic agent, in particular a neutralized phosphoric acid ester, stretching the filaments, applying to the stretched filaments a second spin finish in the form of a dispersion comprising: i) an antistatic agent, ii) a natural or synthetic hydrocarbon wax with a melting point in the range of 40-120 °C, or a wax mixture comprising at least one such hydrocarbon wax and having a melting point in the range of 40-150 °C, and optionally iii) a polydiorganosiloxane, crimping the filaments, drying the filaments, and cutting the filaments to obtain staple fibres, as well as fibres produced by the method and nonwovens prepared from the fibres. The invention allows the production of fibres that have controlled friction and hydrophobic properties and that can be carded at high speeds to result in nonwovens having excellent hydrophobic characteristics.

摘要:
An undersea antifouling agent applied by impregnation for the purpose of preventing aquatic organisms for a long period of time from depositing on, for example, nets for culturing, stationary net fishing, etc., and materials for supporting the net, such as ropes; a net for preventing medusas from invading an intake of sea water for cooling; and materials for shore protection. The first invention relates to an undersea antifouling agent comprising: (A) at least one member selected from among (A1) 2-(thiocyanomethylthis)benzothiazole, (A2) tetraethylthiuram disulfide, (A3) 2,4,5,6-tetrachloro-1,3-dicyanobenzene, (A4) N-(ethylmethylphenyl)dichloromaleimide, and (A5) N-(diethylphenyl)dichloromaleimide; (B) a film-forming material; and (C) at least one compound selected from among dialkyl polysulfides represented by the general formula R₁-(S) n -R₂. The second invention relates to another undersea antifouling agent further comprising the following component (D) polybutene with a degree of polymerization of 2 to 100, in addition to the aforementioned components (A) to (C). The effect of incorporating component (C) and, in addition, component (D) in the antifouling agent resides in that the velocity of releasing component (A) as the active ingredient of the antifouling agent can appropriately be controlled thereby, so that the antifouling effect can be retained for a long period of time.
