Disclosed are thermoplastic blends of polyesteramides and poly(phenylene ether) resins as well as methods for preparing said polyesteramides and polycarbonate blends thereof. Preferred polyesteramides are those comprising amide units of formula (I) ##STR1## and ester units of formula (II) ##STR2## wherein the ratio of (I) to (II) is at least 1:1, and more preferably wherein at least 80% of the units of formula (I) are separated by at least one of the units of formula (II). The thermoplastic blends may additionally contain compatibilizers for the polyesteramide and poly(phenylene ether) resins.

Blends of polyphenylene ethers and polyesteramides

Disclosed are blends of polyesteramides and polyester resins, optionally with polycarbonates, as well as methods for preparing said blends thereof. Preferred polyesteramides are those comprising amide units of formula (I): ##STR1## and ester units of formula (II): ##STR2## wherein the ratio of (I) to (II) is at least 1:1, and more preferably wherein at least 80% of the units of formula (I) are separated by at least one of the units of formula (II).

Blends of polyesters and polyesteramides, optionally with polycarbonates

The invention relates to a polymer mixture comprising A) a polyarylene sulphide, B) an elastomeric polymer having reactive groups which are capable of reacting with the polyarylene sulphide, the polymer mixture moreover comprising as constituent C) a metal salt of a fatty acid having a melting temperature lower than the compounding temperature of the polymer mixture. The presence of the metal salt C contributes to an improvement of the mechanical properties, in particular the ductility.

Polymer mixture comprising polyarylene sulphide elastomeric polymer and

A process for making polyarylene ether-siloxane copolymers is described and the process comprises the step of contacting polyarylene ethers with a hydroxyaromatic or aromatic ether terminated siloxane reagent in the presence of an oxidant.

Method for making copolymers of polyarylene ethers and siloxanes

Improved thermoplastic compositions based on polyphenylene ether are disclosed. These compositions contain a resinous additive derived from a mixture which comprises aromatic monomers, such as a mixture of styrene and alpha methyl styrene. The compositions are characterized by improved melt flow, along with the substantial maintenance of other important properties, such as impact strength and heat distortion temperature.

Polyphenylene ether compositions having improved flow

The invention relates to polymer mixtures which comprise an aromatic polycarbonate, a polyester, and a thermoplastic elastomer. The polymer mixture comprises a polyester-ester urethane or a polyether imide ester as a thermoplastic elastomer. The polymer mixtures according to the invention have good flow properties.

Polymer mixture having aromatic polycarbonate, polyester and

The invention relates to polymer mixtures which comprise a polyphenylene ether, a polyoctenylene and TiO.sub.2 or BaSO.sub.4. The presence of TiO.sub.2 or BaSO.sub.4 leads to an improvement of the mechanical properties.

Polymer mixture which comprises polyphenylene ether, polyoctenylene and

The invention relates to polymer mixtures which comprise a polyphenylene ether, one or more polyesters and a styrene polymer with side chains consisting entirely or partly of cyclic imino ether groups. The polymer mixtures have good properties, in particular a good impact strength in combination with good flow properties and a good chemical resistance.
