Development of Low-Density High Strength Foamed Plastics via Ionic Polymerization

Abstract

Equimolecular mixtures of mono- or di-allyl ethers of trimethylolpropane and sulfur monochloride gave tough, spongy foams when reacted in a halogenated solvent, which also acted as a blowing agent. Reaction was rapid at room temperature, but quite slow at 0 deg F. A number of vinyl alkyl and divinyl ethers were evaluated using cationic catalysts and chlorinated solvents as blowing agents at room temperature. Foams were obtained in a number of cases, and the flexibility of the foams was related to the ratio of the mono-vinyl to the divinyl ether. The foams were quite spongy and friable. Use 3,4-dihydro2H-pyran-2-methanol as a co-monomer with vinyl ethers gave moderately strong, lightweight foams.
