Translation of "Unschmelzbar" in English

This is directly linked with the fact that the polymers are infusible and insoluble.

The green fibres are rendered infusible by this treatment.

After a short period these block copolymers containing hydridosilazane become infusible or insoluble.

The product is insoluble in all solvents and is infusible.

The membranes from acrylonitrile polymers are rendered infusible by this first heat treatment.

The film material obtained is infusible and insoluble in the conventional organic solvents.

The polysilanes can be processed in an outstanding manner into green fibers and are infusible at the processing temperatures.

All of the oxidized polyarylene sulfides in the context of this invention are infusible.

The Spec 44 cables and cables are highly flame retardant, infusible and cold flow resistant.

The solid materials can be fusible or unmeltable and can be soluble or insoluble in organic solvents.

In this process, the polymer is rendered infusible when heating starts and is then pyrolyzed direct.

A further possibility, however, is first to render the polymer infusible and then to pyrolyze it in a subsequent step.

In order to render the ground residue infusible down into the particle core, longer oxidation times are required.

This gives a black-green film which is infusible and insoluble in conventional solvents.

Due to the molecular crosslinking of the insulation, cables according to Spec 44 are infusible even at high temperatures.

According to the present invention, however, it is also possible to use products containing isocyanate groups which are infusible or insoluble.

The term "hardening" is understood to include all condensation and cross-linking reactions which make the resin body unmeltable, so that the bodies can be converted into carbon in a second process step without major changes in shape.

Therefore, it is surprising that the polymers according to this invention do not become brittle and infusible under these conditions. This is particularly so when they are concentrated in an extruder, as may be observed in the case of reaction products of polyisocyanates and cyclic polycarboxylic acid anhydrides.

Following extensive vaporization of the solvent, the filament is then rendered infusible and pyrolyzed, as described above in the case of the fibers spun from the melt.

Following extensive vaporization of the solvent, the coating is then rendered infusible and pyrolyzed, as described above in the case of the fibers spun from the melt.

The resulting fibers were treated with NH3 gas at room temperature to render them infusible and they were then pyrolyzed in a furnace under an NH3 atmosphere.

The polymer fiber was rendered infusible by treatment with NH3 at 25° C. and then heated to 1300° C. over 7 hours under an NH3 atmosphere and pyrolyzed for 1 hour at this temperature, after which the temperature was slowly lowered to room temperature over 5 hours.

Moreover, the hot melt adhesive--due to its still reactive NCO functionality--continues to react in the mixture to give cross-linked products which are very difficult to remove since they are unmeltable and essentially insoluble in the composition, and therefore form deposits.

These blends are suitable for laminates and coatings which crosslink at elevated temperatures and are insoluble or infusible, but not for the preparation of toughened thermoplastics.

This renders the originally thermoplastic copolymer infusible and insoluble in organic solvents, for example toluene, xylene or chlorohydrocarbons.
