Expandable polyetherimide compositions and foamed materials obtained

Substantially closed-cell aliphatic olefin polymer foams having improved dimensional stability are provided by the inclusion therein of from 0.1 to 10 weight percent, based upon the olefin polymer, of certain naphthyl amine compounds.

Foaming synthetic resin compositions stabilized with certain naphthyl

Substantially closed-cell aliphatic olefin polymer foams having improved dimensional stability are provided by the inclusion therein of from 0.1 to 10 weight percent, based upon the olefin polymer, of certain higher aliphatic hydrocarbyl ether, ester or anhydride compounds.

Foaming synthetic resin compositions stabilized with certain higher

Substantially closed-cell aliphatic olefin polymer foams having improved dimensional stability are provided by the inclusion of from 0.1 to 10 weight percent, based on olefin polymer, of an N-higher aliphatic hydrocarbyl substituted amide of a C.sub.1 -C.sub.8 aliphatic carboxylic acid.

Foaming synthetic resin compositions stabilized with N-(higher alkyl)

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.

Foamed thermoplastic resin articles and foamable compositions and

The dimensional stability of closed-cell synthetic polymer foams can be notably improved by the incorporation therein, during their preparation, of from about 0.1 to about 10 percent by weight (based upon the weight of the synthetic resin) of certain borate or phosphinate glycol ester compounds such as, for example, tri(1-stearyl-glycero)borate, tri(monostearylpolyoxyethyleneglycol)borate, di(1-stearylglycero)phosphinate, and the like.

Foamable polymeric compositions
