Abstract
PURPOSE: To obtain a modified rubber useful as a coating material, etc., having improved poerational rate, and adhesive property, capable of giving a film having good properties, and prepared by cyclizing sulfonating, formalizing, halogenating and oxidizing a low-molecular rubber consisting of a specific isoprene-butadiene copolymer.
CONSTITUTION: A low-molecular rubber consisting of an isoprene-butadiene copolymer having weight ratio between the isoprene and butadiene of 95/5W20/80, a molecular weight of 15,000W120,000 and a combined vinyl content ≤35% is dissolved in a solvent, and cyclized in the presence of a catalyst, e.g. sulfuric acid, under heating, sulfonated with sulfur dioxide, etc. under heating, formalized with formaldehyde under heating, halogenated with chlorine or bromine under heating and oxidized with a peroxide under heating to give the aimed modified rubber.
