ABSTRACT:
A mixture of an isomer of 2,2'-azobis(2,4-dimethylvaleronitrile) having a low melting point in an amount of about 70% by weight or more and an isomer of 2,2'-azobis(2,4-dimethylvaleronitrile) having a high melting point in an amount of about 30% by weight or less shows excellent solvent solubility, which is higher than that of the isomer having a low melting point. The mixture is useful as a polymerization initiator, and also as a blowing agent.
