摘要： PROBLEM TO BE SOLVED: To obtain a new compound having excellent solubilities not only in organic solvents but also in water in response to the conditions of pH and temperature, etc., and useful as a copolymerization component for acrylamide polymers used for paper production additives. SOLUTION: An amphipathic compound of formula I or II (R1 is a 6-48C saturated hydrocarbon, an unsaturated hydrocarbon containing one to twelve unsaturated double bonds, etc.; R is a 2-6C saturated hydrocarbon; R3 is H, methyl; M is H, an alkali metal, etc.). The compound is obtained by reacting a hydroxyalkyl acrylate or methacrylate with the reaction product of maleic anhydride with an olefin oligomer in a solvent-free system or organic solvent system.

摘要： PROBLEM TO BE SOLVED: To obtain a new compound useful as a polymerizable surfactant and a paper additive. SOLUTION: This N-monoallyl-substituted oligopropenylsuccinic acid half amide compound is expressed by formula I, formula II (R1 and R2 are each H or a group of formula III; (n) is 0-6; M is H, an alkali metal, an alkaline earth metal, ammonium or an organic base), etc. The compound is a hydrophobic compound soluble in organic solvents and is also an amphiphatic compound exhibiting water-solubility or water-dispersibility according to the pH, temperature conditions, etc., owing to carbonyl group and amide group existing in the molecule. It is polymerizable with various vinyl compounds and useful as a raw material for synthetic resins. Especially a copolymer with (meth) acrylamide is useful as a paper additive soluble or dispersible in water and having excellent paper-strengthening property and sizing performance. The compound of formula I or formula II can be produced by using an oligopropenylsuccinic anhydride as a raw material and reacting with allylamine or diallylamine in the absence of solvent or in an organic solvent.

摘要： PURPOSE: To perform an adiabatic reaction in good precision even in a polymerization reaction of a high polymerization speed by markedly improving the response speed by filling the outside of the reaction system with an aqueous medium and using high-frequency for heating this medium. CONSTITUTION: This polymerizer is the one for performing an exothermic polymerization reaction and composed of a polymerization tank 10, a jacket 12 for performing the temperature control of the tank 10 and a pump 18 for withdrawing the aqueous medium 2 from the jacket 12 and recirculating the withdrawn medium to the jacket 12 through a heater 20 and a cooler 19, wherein the heater 20 is a high-frequency heater. In this polymerizer, an aqueous medium is used as the medium outside the reaction system, the aqueous medium is heated by high-frequency while it is being recirculated. Therefore, the temperature of the aqueous medium can be raised instantly in response to the temperature inside the reaction system, and the temperature rise can be stopped instantly by breaking the electric source for high-frequency to maintain easily the temperature constant. Therefore, by controlling only the outside temperature, a polymer different in properties such as a molecular weight can be obtained in good reproducibility.
