摘要： In a process for preparing polyarylene sulfides by reacting a dihalo-aromatic compound with a sulfur source in an organic amide solvent in the presence of an alkali metal salt of carboxylic acid as a polymerization aid or assistant, a specific class of carboxylic acids are employed for preparing the alkali metal salt polymerization aid. The specific carboxylic acids are of the general formula: R(COOH).sub.n (wherein R is a C.sub.1 -C.sub.20 organic radical and n is an integer not less than 1) and have a solubility of not less than 3 g/100 ml in ethanol at 20.degree. C. Use of such a carboxylic acid in the process permits the recovery thereof from the polymerization mixture to be effected with significantly improved efficiency.

摘要： In a process for partially curing a powdery polyarylene sulfide resin which comprises heating the powdery resin either in the absence or presence of oxygen while agitating so as to attain an increased melt viscosity in a range suitable for further processing or molding of the resin, an improvement comprising that the resin together with an added specific inorganic additive undergoes the partial curing treatment at temperatures in the range of from a temperature just below the melting point of the starting resin down to a temperature lower by 80.degree. C. than said melting point. The additive is selected from the group consisting of silica, hydrophobic silica, talc and calcium carbonate and mixtures thereof. By use of the additive, the powder characteristics or fluidity properties of the starting resin are substantially retained during and after the partial curing treatment, the static electricity generated by agitation of the resin during the treatment is significantly reduced, and the resin is effectively prevented from forming scaling on the interior walls of the reactor vessel used for the process. Therefore, the agitation of the powdery resin can be uniformly and efficiently effected so that a desired control of the melt viscosity is easily achieved.

摘要： In a process in which a poly (arylene sulfide) is synthesized by reacting a dihaloaromatic compound and an alkali metal sulfide in a polar organic solvent, the curing ability of the product polymer is significantly enhanced by introducing a small proportion of a hydroxyl group-containing polyhaloaromatic compound to the reaction mixture when a conversion of at least 60% has been achieved with respect to the dihaloaromatic compound present in the reaction mixture. The product polymer may be advantageously employed in various molding, forming or coating processes to provide the produced articles with increased strengths. The hydroxyl groups introduced into the polymer enable the polymer to be modified, if desired.

摘要： A polyarylene sulfide having a high molecular weight is produced at low cost and without causing any pollution problems through a polymerization reaction between a dihalogenated aromatic compound and an alkali metal sulfide in an aprotic polar solvent by adding from about 0.05 to about 5 moles of calcium chloride per mole of the dihalogenated aromatic compound after the conversion of the dihalogenated aromatic compound has reached about 60 to about 98 mol % and allowing the reaction to proceed. Such a polyarylene sulfide is very useful for utilization in extrusion of films, fibers, etc.

摘要： A highly modified polyphenylene sulfide (hereinafter refer to as "PPS") which contains covalently bonded chlorine in a far less amount than conventional PPS's and is substantially free from ionically bonded chlorine and sodium, is produced by heat-treating a conventional PPS with at least one of organic, sulfur-containing compounds in a solvent capable of dissolving the PPS. Such a PPS is very useful as a coating or encapsulating material for electrical and electronic components, etc.

摘要： A zero-crossing detector compares a neutral node voltage of a motor with a back electromotive force of at least one of windings and outputs a first signal every time a zero-crossing is detected as a result of the comparison. A cycle detector detects a cycle of the first signal and outputs a second signal during a final portion of the cycle. A de-energizer de-energizes all the windings of the motor during at least a period of time that the second signal is being output. The zero-crossing detector performs detection of a zero-crossing during the period of time that the second signal is being output.
