3-Methyl-1,3-Pentadiene

Abstract

3-Methyl-1,3-pentadiene can be prepared pure without difficulty. However, unlike butadiene, isoprene, piperylene, and 2,3-dimethyl-1,3-butadiene, it apparently does not polymerize to an elastic, resilient solid product, and therefore the polymerization of 1,3-dienes to rubber-like products does not depend solely on the presence of the vinyl group.
