Suppressing cyclic amide(s) evapn. in polyamide prodn. and processing
A method for the prodn. and processing of polyamides comprising adding zeolites and/or other aluminous substances (I) to the polyamide in amts. sufficient to absorb low-mol. wt. cylic amides (II) and thus render them largely involatile. The addn. of (I) can take place at any time provided that \- on...

Summary: | A method for the prodn. and processing of polyamides comprising adding zeolites and/or other aluminous substances (I) to the polyamide in amts. sufficient to absorb low-mol. wt. cylic amides (II) and thus render them largely involatile. The addn. of (I) can take place at any time provided that \- one stage is completed in which a polyamide with the required properties is produced. |
