Polymeric compositions characterized by their excellent thermal stability containing a polyphenylene ether or one of its blends with at least one (co)polymer of styrene and at least one compound belonging to the group of linear and/or cyclic beta diketones. Beta-diketones are capable of giving polyphenylene ether and/or its blends with styrenic polymers a long-lasting thermal stability in the molten state and of guaranteeing sufficient fluidity to ensure better processability compared to the same polymers in the known art.

Compositions of polyphenylene oxide or mixtures of polyphenylene oxide

Polymeric compositions based on at least one polyphenylene ether, obtained from the (co)polymerization by oxidative coupling of one or more substituted phenols, either alone and/or together with at least one (co)polymer of styrene, are thermically stabilized by adding at least one compound having the structural formula

Self-extinguishing polycarbonates consisting of mixtures of polycarbonates with at least one salt of particular carboxylic organic compounds, said salt being of metals of Group I A and/or B, and/or Group II A and/or B of the Periodic Table of elements, and/or of ammonium.

Self-extinguishing polycarbonate composition

Self-extinguishing polycarbonates are disclosed, which consist of mixtures of polycarbonates with at least one salt of metals of the I and/or the II A and B Groups of the Periodic Table, and/or ammonium salts of organic carboxylic compounds having the general formula (I) ##STR1## and, as an adjuvant, at least one compound which is a member selected from the group consisting of the following classes of compounds:

Novel thermoplastic elastomers are disclosed, which are based on copolyesteramides and are composed by a statistically distributed array of soft and hard molecular chains, bonded to each other by ester bonds. These thermoplastic elastomers have shown an improved resistance to heat and hydrocarbonaceous fluids such as fuels, lubricants and the like.
