A process for tempering edible plastic fat products such as margarine and shortenings which comprises crystallizing with cooling a starting material of fats and oils with or without other ingredients and subjecting the resulting product to pressuring treatment.

In a process of emulsion-polymerization in a polymerization system containing an acrylate or a methacrylate monomer at least 60%; the improvement which comprises carrying out the emulsion polymerization in a polymerization vessel having a film of a quinone-amine compound of not less than 3000 in average molecular weight on the inner vessel wall, said quinone-amine compound being prepared by addition-reacting an aromatic quinone and an aromatic diamine in a solvent medium having a solubility parameter of 9.0 to 12.2. According to the process, the polymer scale deposition can be prevented in the acrylate or methacrylate polymerization system.

Process for polymerization of acrylate or methacrylate

A continuous suspension polymerization process for the production of polymeric particles substantially uniform particle size, entailing the steps of forming monomer droplets of substantially uniform particle size through an orifice under vibration, and effecting polymerization of the monomer droplets in an aqueous medium. The process permits carrying out polymerization without destruction or agglomeration of the monomer droplets, so that the particle size of the polymeric particles thus produced depends predominantly upon the particle size of the monomer droplets as initially formed.

A method of measuring a combustible component in a liquid or gas employs a gas having a high oxygen content, instead of air or an inert gas, as the carrier gas to thereby improve drastically the scope and accuracy of measurement by a semicondutor gas sensor. The carrier gas having a high oxygen content is supplied into a combustible component sampler formed from a gas-permeable membrane and disposed in the liquid or gas to be tested so that the combustible component may be diffused into the carrier gas through the gas-permeable membrane. The carrier gas entraining the combustible component therein is introduced into a detector having a semiconductor gas sensor, in which the combustible component is detected, and its concentration is determined continuously or intermittently.

In a process for preparing foamable synthetic resin granules by suspension polymerization, a fatty acid bisamide is added prior to or at an early stage of polymerization in the presence of an inorganic salt and a foaming agent is added at a later stage of polymerization or after completion thereof.
