    • A powdery linear polymer having a narrow particle size distribution with little dusting and excellent in anti-blocking property is recovered from a latex of a linear polymer containing a large proportion (35–75 wt. %) of soft polymer (S) component through a two-step coagulation process including a first (moderate coagulation) step causing 70–98 wt. % of the coagulation. The linear polymer in the latex has a multilayer structure comprising a linear polymer (S) having a glass transition temperature below 40° C. and a linear polymer (H) having a higher glass transition temperature disposed in totally at least two layers and containing 35–75 wt. %, as a whole, of the linear polymer (S) with the proviso that the linear polymer (S) cannot be contained in excess of 30 wt. % in an outermost layer of the multilayer structure.

    • The object of the present invention is to provide a recycled molded article, not having defects such as sink, warping, bending, and the like, and whose molding contraction does not change substantially depending on its recycle turn number so that said molded article having a good dimensional stability can be manufactured without changing design of the injection molding machine or molding conditions in every turn. To attain this object, the gas assist injection molding method or the expansion injection molding method wherein gas pressure or expansion pressure is effected on the melted molding material mixture in the mold, are applied in the present invention. By applying these methods, the melted molding material mixture may fill the mold uniformly and contraction strain by cooling may be absorbed in the inner hollow or the foamed structure in the resulting molded article, and further change of mold contraction depending on recycle turn number is reduced to obtain a molded article having a good dimension stability.
    • 本发明的目的是提供一种不具有凹陷,翘曲,弯曲等缺陷的再循环成型品,其成型收缩根据其循环回转数不发生显着变化, 可以在不改变注塑机的设计或每一轮的成型条件的情况下制造良好的尺寸稳定性。 为了达到上述目的,在本发明中应用气体辅助注射成型法或膨胀注射成型法,其中在模具中熔融的成型材料混合物上进行气体压力或膨胀压力。 通过应用这些方法,熔融的成型材料混合物可以均匀地填充模具,通过冷却的收缩应变可以被吸收到所得模制品中的内部中空或发泡结构中,并且根据再循环转数而进一步改变模具收缩 以获得具有良好尺寸稳定性的模塑制品。

    • The object of the present invention is to provide a molding thermoplastic resin material giving resin mold whose quality and value are substantially equal to original resin mold even in a case where said resin mold is recycled. To attain said object, olefin group rubber and/or acrylic rubber to which monomer(s) being the same or similar monomer as (to) monomer(s) composing said molding thermoplastic resin material is(are) graft-copolymerized to give said rubbers compatibility with said molding thermoplastic resin material is(are) added in said molding thermoplastic resin material to improve said equal quality recycling property (property that quality and value are substantially equal to original thermoplastic resin mold even in a case where said thermoplastic resin mold is recycled). Said olefin group rubber and/or said acrylic rubber has(have) excellent thermal stability, heat-resistance, ozone resistance, oxidation resistance, and durability and has(have) effect on improvement of impact resistance for said thermoplastic resin material which is substantially immutable against heat history affected by repeated recycles and said molding thermoplastic resin material of the present invention can be used as a resin material of equal quality resin mold whose quality and value are substantially equal to resin mold using virgin resin material even in a case where said resin mold is recycled.
