Abstract: PROBLEM TO BE SOLVED: To provide a method for easily producing a polymer particle dispersion in which the polymer particles are dispersed in a non-aqueous solvent. SOLUTION: This method for producing a polymer particle dispersion in which the polymer particles are dispersed in a non-aqueous solvent comprises subjecting a polymerizable monomer having a vinyl group to a suspension polymerization in the presence of an ammonium salt type surfactant as a dispersing agent in an aqueous solvent, subjecting the obtained polymer suspension to the addition of the non-aqueous solvent and the ammonium salt-removing treatment of the ammonium salt type surfactant, and dehydrating the product before, after or during the ammonium salt-removing treatment.

Abstract: PURPOSE:To obtain a new modified polyethylene having a polar and highly reactive functional group near the middle part of the molecule in high purity by performing living polymerization of ethylene using an alkyllithium/t-diamine initiator and reacting the product with a formic acid ester. CONSTITUTION:Ethylene is subjected to living polymerization in the presence of an initiator consisting of a 1-6C straight or a branched alkyllithium (e.g. methyllithium) and a t-diamine (preferably tetramethylethylenediamine, etc.) preferably at 20-80 deg.C generally for 0.1-24hr. The polymerization product is reacted with a formic acid ester preferably by slowly adding the ester little by little to the system to obtain the objective polyethylene having a functional group near the middle part of the molecular chain and expressed by the formula (R) is a 1-6C straight or a branched saturated hydrocarbon chain; (m) and (n) are 10-1,000; A is H or a alkali metal). The living polymerization is preferably carried out by introducing ethylene into a cyclohexane solution containing the initiator under a pressure of 1-100kg/cm .

Abstract: PURPOSE:To obtain a bathing agent composition capable of sustaining aroma of constant quality and intensity for a long period after introducing the aforementioned composition into bath water containing a microencapsulated and an unmicroencapsulated perfumes. CONSTITUTION:A bathing agent composition is obtained by including a microencapsulated perfume using a polymer, e.g. a copolymer of (meth)acrylic acid and an acrylic or a methacrylic acid ester capable of dissolving at a normal bath temperature, i.e., 37-43 deg.C after a prescribed time as a wall material and an unmicroencapsulated perfume, preferably occluded and impregnated in a porous substance, oil absorbing powder, etc. It is effective to slowly scent the highly volatile perfume with the microcapsules and scent the low volatile perfume from the substance impregnated with the perfume. Copolymers of (meth) acrylic acid-methyl (meth)acrylate are preferred as the aforementioned wall material and dissolution rate and the duration of the aroma can be controlled within a wide pH range in taking a bath by changing composition ratio thereof.

Abstract: PROBLEM TO BE SOLVED: To obtain a glyceric acid polymer with controlled degree of branching and to provide a manufacturing method therefor. SOLUTION: The glyceric acid polymer is prepared by forming ester bonds between the carboxylic group of glyceric acid and its primary and/or secondary hydroxy group. The degree of branching (DB) defined by calculation formula (1): (DB) = 2B/[2B+(L-1)+(L-2)] of the polymer is 0.8 or lower, and the average polymerization degree (n) defined by calculation formula (2): (n) = [(L-1)+(L-2)+B+T]/[T-B] is in the range of 1.1-1,000. In the calculation formulas, L-1 is the number of straight chain units bonded only by primary hydroxy groups; L-2 is the number of straight chain units bonded only by secondary hydroxy groups; B is the number of branched units bonded by primary and secondary hydroxy groups; and T is the number of terminal units which do not react with both of primary and secondary hydroxy groups.
