Thermoplastic molding composition

The instant invention pertains to the use of an antistatic composition comprising a polar thermoplastic polymer and an ionic liquid as antistatic additive for non-polar thermo-plastic or elastomeric polymers. Further aspects of the invention are a process for the preparation of an antistatic non-polar thermoplastic or elastomeric polymer which process comprises incorporating therein a mixture of a polar thermoplastic polymer and an ionic liquid and the composition of a polar thermoplastic polymer, an ionic liquid and a non-polar thermoplastic or elastomeric polymer.

Antistatic thermoplastic compositions

The present invention relates to a process for the production of polyarylene ether block copolymers comprising, in a first stage, the reaction of at least one aromatic dihydroxy compound comprising 4,4'-dihydroxybiphenyl in a molar excess and of at least one aromatic dihalogen compound, to form a polybiphenyl sulfone polymer, and then, in a second stage, the reaction of the polybiphenyl sulfone polymer with at least one aromatic dihydroxy compound and of at least one aromatic dihalogen compound. The invention further relates to the resultant polyarylene sulfone block copolymers and to the use of the polyarylene sulfone block copolymers for the production of moldings, fibers, films, or foams.

Method for producing poly(arylene ether) block copolymers

The invention relates to processes for the production of a composite component via multicomponent injection molding, where the composite component comprises a main body composed of a thermoplastic and an external layer composed of a foamed thermoplastic. The main body is produced via injection molding and subsequent hardening of the thermoplastic. A mixture of the foamed thermoplastic and a chemical blowing agent is injected onto the main body, subsequently hardened in the same injection mold, and foamed by heating. The composite component is solidified via cooling. The foamed thermoplastic is at least one polyamide whose modulus of elasticity is from 1 MPa to 250 MPa in the entire temperature range from 70&#xb0; C. to 180&#xb0; C. The chemical blowing agent is in non-polymerized form.

Method for producing a composite component by multi-component injection molding

The present invention relates to polyarylene ether block copolymers according to the general formula A-K&#x2014;X&#x2014;K-A, where &#x2014;X&#x2014; is a polyarylene ether segment with number-average molar mass of at least 5000 g/mol, and A- is a segment of the general structure RNH&#x2014;(R&#x2014;NH&#x2014;CO&#x2014;Ar&#x2014;CO&#x2014;NH)&#x2014;R&#x2014;NH&#x2014;, in which Ris a linear or branched alkylene group having from 2 to 12 carbon atoms and Ar is an arylene group having from 6 to 18 carbon atoms, and Ris selected from aryloyl, alkyloyl, and H, and in which the number average of n is from 1 to 3, and there is a coupling group K of the structure &#x2014;CO&#x2014;Ar&#x2014;CO&#x2014; linking each A to X, in which Aris an aromatic group having from 6 to 18 carbon atoms. The present invention also relates to a process for the production of the polyarylene ether block copolymers of the invention, to polymer compositions comprising the polyarylene ether block copolymers of the invention, and also to the use thereof for the production of moldings, of films, of fibers, or of foams.
