    摘要: The invention relates to a process for the preparation of an N-alkyl or N-aryl carbamoyl derivative in which an amine is contacted with a carbonic acid derivative according to the general formula: where fragments X in the form of XH are a lactam, oxime, imide or triazole. In particular the invention relates to the preparation of a blocked isocyanate according to a process in which no isocyanate is used. The invention also relates to the use of the N-alkyl or N-aryl carbamoyl derivative prepared according to the process according to the invention in a coating.

    摘要: The invention relates to a process for preparing a high-molecular polyamide or polyester by melt-mixing polyamide or polyester having a lower molecular weight with a carbonyl bislactam having formula 1, in which n=an integer of between 3 and 15. With the process according to the invention a permanent increase in the molecular weight of a polyamide is obtained within 2 minutes, whereas this takes at least 10 minutes under comparable conditions using a bislactam according to the state of the art.

    摘要: A high molecular weight polyester-amide block copolymer is produced by reacting a mixture of lower molecular weight polyester and polyamide in the melt with a carbonyl bislactam, especially carbonyl biscaprolactam. The higher molecular weight block copolymer may be obtained in as short a time as 2 minutes, whereas, at least about 10 minutes is required in a conventional process, under comparable conditions, using a bislactam.

    摘要: The invention relates to a compound comprising a reaction product of (A) an isocyanate functional compound of which at least 40 wt. %, relative to the total amount of (A), has a molecular weight of at least about 500, and (B) a nitrogen-containing compound capable of reacting with said isocyanate functional compound (A). The reaction product has a molecular weight of less then about 20,000 and comprises an effective amount of groups that are able to form reversible intermolecular physical interactions such that a resulting compound shows polymeric mechanical properties at a temperature below a transition temperature. The nitrogen-containing compound is, for instance, melamine, urea, acetoguanamine, benzoguanamine, cyanamide, dicyanamide, thiourea, isocytosine, pyrimidone or aminopyridine. The supramolecular compound comprising a suitable amount of the reaction products exhibits a relatively high elongation at break.
