ABSTRACT:
Thermoplastic compositions having improved melt strength comprise a polyphenylene ether polymer and a polyamide. The polyamide is formed from a diamine, a second amine selected from secondary triamines and polyamines, and a dicarbioxylic acid. The second amine is included in an amount sufficient to improve the melt strength of the composition. The compositions are particularly suitable for use in blow molding processes.
