摘要： PURPOSE:To enhance cleanability, triboelectrification stability, resistances to blocking and offset by adding an aq. dispersion of an offset inhibitor during polymn., at the time of >=90wt% polymn., before or after solidification. CONSTITUTION:The aq. dispersion of the offset inhibitor is added during polymn., at the time of >=90wt% polymn., before and/or after solidification at the time of preparing an electrophotographic toner, and polymn. is conducted after emulsification dispersion or during it at a temp. of 20-120 deg.C, and a cross- linking agent is added in an amt. of 0-20wt% of the total polymerizable monomer, and a mixing ratio of monomer to aq. medium is, preferably, 40/60-90/10 by weight. An emulsifier is added to the monomer in an amt. of 0.01-10wt%, and a polymerization initiator is added in an amt. of 0.01-10wt%, thus permitting the obtained electrophotographic toner to be superior in cleanability, triboelectrification stability, and blocking resistance, suitable for dry development, and prevented from offset trouble, and the obtained image to be superior in resolution, image density, and gradation.

摘要： PURPOSE:To produce a coagulated latex free of impurities such as a precipitant or emulsifier-derived products, by adding a specified precipitant to an emulsion polymer latex obtained by using a carboxylate emulsifier and neutralizing it. CONSTITUTION:In the production of a coagulated latex from a polymer latex (e.g., ABS resin latex) obtained by emulsion polymerization by using an emulsifier in which the hydrophilic group is a carboxylate (e.g., potassium stearate), the polymer latex is precipitated by adding thereto a precipitant containing 0.05-50 equivalent, in relation to the carboxylate groups of the emulsifier, of an acid (e.g., hydrochloric acid) and 0.05-20 equivalent of a water-soluble salt of a bi- or trivalent metal (e.g., CaCl2 or AlCl3), and then neutralized by adding 0.5-5 equivalent, in relation to the added acid, of a base (e.g., NaOH). The polymer thus produced is freed from problems such as discoloration, corrosion of a die or the like, during molding, because the carboxylic acids which are emulsifier derivatives formed from the emulsifier and the precipitant are stabilized and the impurity content of the final polymer is reduced because of a small amount of the added polyvalent metal salt.

摘要： PURPOSE: To prevent polymer scale deposition, by coating areas in contact with a polymer latex, such as walls of a vessel or a pipe, with a scale deposition preventing agent comprising a dye and a silicaceous compound and drying it.
CONSTITUTION: A scale deposition preventing agent is obtained by mixing a dye such as a direct dye, acid dye, basic dye, sulfide dye, vat dye, or optical brightener (e.g., C.I. Direct Yellow 26) with a silicaceous compound (e.g., colloidal silica) at a weight ratio of 1:0.01W10. 0.01W5wt% this agent is dissolved in a solvent (e.g., methanol), and the solution is applied to an area in contact with a polymer latex, such as a wall of a vessel or a wall of a pipe, so that the amount of the agent, after drying, may be at least 0.001g/m
2 , dried at room temperature W100°C and, if necessary, washed with water.

摘要： PURPOSE: To recover particulate aggregates of PVC in high yields, by adding coarser PVC particles to an aqueous dispersion of PVC for processing into a paste, and mixing the resulting dispersion with an organic liquid which is difficultly soluble in water and neither dissolves nor swells PVC.
CONSTITUTION: PVC of an average particle diameter of 10W60μ in an amount of 1W70wt%, based on the total weight of resin, is added to an aqueous dispersion of PVC for paste technique. To the resulting dispersion is added an organic liquid which is difficultly soluble in water and neither dissolves nor swells PVC (e.g., dioctyl phthalate, trioctyl trimellitate, butyl oleate, or liquid paraffin). In this way, it is possible to obtain particulate aggregates of PVC in extremely high yields, and further to facilitate markedly the recovery of the resinous matter contained in the aqueous layer left after separating the particulate polymer.

摘要： PURPOSE:To recover efficiently a thermoplastic resin having a sharp particle size distribution and a practically spherical particle form from a thermoplastic resin emulsion by adding a coagulant, etc., in a specified two-step process. CONSTITUTION:In step 1, a coagulant (e.g., sulfuric acid) and/or a coagulation aid (e.g., polyethylene oxide) are added to a thermoplastic resin emulsion to bring the emulsion into the state of an incomplete coagulation (the pH of the slurry being preferably about 3-7). In step 2, a coagulant (optionally, together with a coagulation aid) is added and the mixture is treated at a temperature which is about 10 deg.C above that 1 in step (preferably, at a pH of about 2-7) to recover the thermoplastic resin.
