The dimensional stability, especially at elevated temperatures such as 70.degree. C., of thermoplastic resin foams, such as those of aliphatic olefin polymers, is substantially improved by the inclusion therein of from 0.01 to 5 weight percent, based upon said resin, of certain benzylideneaniline derivatives, azobenzene derivatives, azooxybenzene derivatives and the like.
