  • Child car seat
    Patent number: 9022470
    Abstract: A child car seat (10) includes a child-car-seat body (15) includes a seat part (40) having a seat plate part (41) and a back plate part (45), a sliding member (60) located on a position opposed to the back plate part from a front side, the sliding member being slidable with respect to the back plate part so as to move in a height direction, and a child belt disposed on the child car-seat body. The sliding member (60) has a through-hole (66) through which the child belt (30) can pass. The back plate part has, at a position opposed to the through-hole, an elongate hole (66) extending in a sliding direction of the sliding member with respect to the back plate part.

  • Graft copolymer having dispersion stabilizing effect, a process for producing the same, and a process of emulsion polymerization using the same
    Patent number: 4988771
    Abstract: A graft copolymer having dispersion stabilizing effect, which comprises on the carbon backbone thereof a polymer side chain comprising a carbon chain having a molecular weight of 1,000.about.100,000, a fluorine atom containing fluorine side chain and a hydrophilic side chain containing a hydrophilic group, the total mean molecular weight of said graft copolymer being 5,000 or more. The graft copolymer of this invention can be used as an excellent dispersion stabilizer for emulsion polymerization, whereby in emulsion polymerization it is possible to attain polymer particle dispersion stability to ensure that the polymer particles will not be agglomerated even if they have been grown to larger particles having a diameter of 0.5.mu. or more and that dispersion of the polymer particles having a large and uniform particle diameter is obtained.

  • Graft copolymer having dispersion stabilizing effect, a process for producing the same, and a process of emulsion polymerization using the same
    Patent number: 4916191
    Abstract: A graft copolymer having dispersion stabilizing effect, which is a product of the polymerization of 5 to 30% by weight of a macromonomer which has a molecular weight of 1,000 to 100,000 and has a radical polymerizable unsaturated group at its one end, 1 to 40% by weight of a hydrophillic monomer which has a hydrophillic moiety in it and has a radical polymerizable unsaturated group, and 5 to 40% by weight of a fluorinated monomer which has a florinated moiety in it and has a radical polymerizable unsaturated group, the % by weight being based on a total of the three monomers, and 0 to 50% of the total of the total of the three monomers of a monomer copolymerizable therewith.
