Method and device for producing three-dimensional objects in layers, comprising treating pulverulent, in particular, polymer, substrates or polymerizable monomers by means of microwave radiation.

Method and device for producing three-dimensional objects

The invention relates to a process for the production of molding compositions from a thermoplastic polycondensation resin susceptible to degradation at high temperature in the presence of H.sub.2 O, to which is admixed a second synthetic resin, present as an aqueous latex, at temperatures in the range of 150.degree.-300.degree. C. and under a pressure in the range of 1-100 bar under the effect of high shear forces, for a time sufficient to provide the desired molding composition without substantially degrading the polycondensation resin.

Polyesters are modified by adding an aqueous latex having a solids content of &lt;50% by weight. The synthetic resin contained in the latex has a glass transition temperature of .ltoreq.0.degree. C. and contains 0.1-20 mol-% of functional groups.

Molding compositions based on linear, high-molecular weight polyesters

A thermoplastic resin composition, which comprises (a) from 5 to 85 parts by weight of a melted or remelted preliminary molding compound consisting of from 60 to 98 parts by weight of polyphenylene ethers, 40 to 2 parts by weight of polyoctylenes, from 0.1 to 5 parts by weight of maleic anhydride and from 0.1 to 5 parts by weight of a further acid derivative which has a melting point below 100.degree. C. and which is selected from the group consisting of an unsaturated mono- or dicarboxylic acid having up to 14 carbon atoms, an anhydride thereof, which excludes maleic anhydride, and an ester of mono- or dicarboxylic acid with an alcohol of up to 6 carbon atoms; and (b) from 95 to 15 parts by weight of an aliphatic homopolyamide or a copolyamide containing a preponderant amount of aliphatic monomer units.

Impact-resistant thermoplastic molding compounds based on polyphenylene

The invention relates to a process for the production of molding compositions from a thermoplastic polycondensation resin susceptible to degredation at high temperature in the presence of H.sub.2 O, to which is admixed a second synthetic resin, present as an aqueous latex, at temperatures in the range of 150.degree.-300.degree. C. and under a pressure in the range of 1-100 bar under the effect of high shear forces, for a time sufficient to provide the desired molding composition without substantially degrading the polycondensation resin.

Hydrolysis-resistant, thermoplastic molding compositions are made from high-molecular weight, linear polybutylene terephthalate and 0.1-10 mole %, based on the amount of the dicarboxylic acid component of the polyester, of a salt of Formula (A)
