    • The invention provides a novel and improved method for the preparation of a cellular foamed body of a vinyl chloride-based resin having a very fine and uniform cellular structure with high productivity in a continuous process. According to the inventive method, a vinyl chloride-based resin is admixed with a nucleating agent and a foam conditioning resin which is a specified acrylic resin or a styrene-based resin into a resin composition and the resin composition is first heated under pressure to be converted into an at least partly gelled mass, into which a volatilizable foaming agent which is an organic solvent having a boiling point not exceeding 90.degree. C. is injected under pressure so as that the resin composition is uniformly impregnated with the foaming agent. The foaming agent-impregnated and completely gelled resin composition is then brought under a reduced pressure to be expanded into foams with simultaneous cooling.The above process is most conveniently practiced by use of an extruder machine in which the volatilizable foaming agent is continuously injected into the cylinder where the heated and gelled resin composition is running.
    • 本发明提供了一种制备具有非常细且均匀的细胞结构的氯乙烯基树脂的细胞发泡体的新颖和改进的方法,在连续方法中具有高生产率。 根据本发明的方法,将氯乙烯类树脂与作为特定丙烯酸树脂或苯乙烯类树脂的成核剂和泡沫调理树脂混合到树脂组合物中,并将树脂组合物首先在压力下加热至 转化为至少部分凝胶状物质,在压力下注入作为沸点不超过90℃的有机溶剂的可挥发泡沫剂,以使树脂组合物均匀地浸渍有发泡剂。 然后将发泡剂浸渍和完全凝胶化的树脂组合物在减压下进行膨胀,同时冷却扩展成泡沫。 上述方法最方便地通过使用其中将可挥发泡沫剂连续注入到加热和凝胶化树脂组合物运行的圆筒中的挤出机来实现。

    • An improved method for the polymerization of vinyl chloride or a monomer mixture mainly composed of vinyl chloride in an aqueous polymerization medium is proposed in which a water-insoluble polymerization initiator, being solid at room temperature as dispersed in the aqueous medium and having a particle size distribution of 50 .mu.m or finer, is added to the polymerization mixture which is maintained at a temperature where the half-life period of the initiator is 120 minutes or longer or, alternatively, over a duration equal to or shorter than one-tenth of the half-life period of the initiator at the temperature of the polymerization mixture. By this method the polymerization can be homogeneously proceeded to produce vinyl chloride polymers having a uniform particle size distribution, excellent heat stability and much less fish-eyes when fabricated into sheets.

    • Upon receipt of a direction indication control signal s11, a sounding-body driving circuit 12 generates a driving signal s16 for generating a flashing operation sound which is an artificial striking sound similar to a striking sound of a mechanical relay. The driving signal s16 is output to a speaker 16 via an amplifier 14, and the flashing operation sound is outputted from the speaker 16, thereby obtaining the flashing operation sound which does not sound unusual to the driver. The sounding-body driving circuit 12 enables a plurality of rectangular wave signals having the same amplitude and different frequencies to be synthesized in sequence of time by first and second synthetic signal generating circuits 20A and 20B to thus generate first and second synthetic signals s14 and s15 as artificial striking sounds.

    • A process for preparation of a vinyl chloride polymer comprising the steps of subjecting an aqueous medium containing vinyl chloride monomer or a mixture of vinyl chloride monomer with other vinyl monomer, a polymerization initiator and a dispersant to high-speed shear agitation at a shear rate of 10.sup.4 sec.sup.-1 or above to prepare a suspended dispersion containing fine particles of the monomer(s) dispersed therein, then subjecting the suspended dispersion to low-speed shear agitation at a shear rate of from 10 to 100 sec.sup.-1, and thereafter starting suspension polymerization. Even with a decreased amount of dispersant, the process inhibits the coarsening of the polymer particles, to yield the polymer with a narrow particle diameter distribution. Deposition of scale and formation of fish-eyes are also prevented effectively.
