SUPRAMOLECULAR NETWORK THERMO-REVERSIBLE CROSSLINKED ELASTOMER THROUGH IONIC INTERACTION OF AROMATIC CARBOXYLIC ACID AND METHOD PRODUCING THEREOF

摘要

PURPOSE: A supermolecular thermo-reversible crosslinked elastomer composition is provided to have elasticity and physical properties similar with crosslinked rubber, to be reversible by heat at 150 C or higher, to be repeatedly used, and to prevent physical property loss after repeated uses. CONSTITUTION: A supermolecular thermo-reversible crosslinked elastomer composition is obtained by grafting 0.15-25 parts by weight of an aromatic unsaturated carboxylic acid to 100.0 parts by weight of an elastic rubber including a double bond in the molecule, adding 0.1-1.0 parts by weight of an antioxidant and 0.15-25 parts by weight of a metal salt into the same, and conducting a reaction. The elastic rubber is one or a mixture of two or more among a butadiene rubber, an isoprene rubber, a styrene-butadiene rubber, a nitrile rubber, a chloroprene rubber, an ethylene-propylene rubber, an ethylene-propylene-diene rubber, a butyl rubber, and an acryl rubber.
