ADDITIVES MADE FROM FATTY DIAMIDES FOR NUCLEOPHILE-SENSITIVE CROSS-LINKABLE COMPOSITIONS

摘要

The present invention relates to a composition based on fatty acid diamide comprising: a) from 92% to 100% by weight of one or more fatty acid diamides, treated in situ by a neutralizing agent so as to reduce the residual amine content to a residual amine number, expressed in mg KOH/g, which remains less than 0.5, b) optionally, up to 8% by weight of at least one amorphous or semicrystalline oligomer with a Tg of greater than 60° C., with the sum of the % by weight a)+b) being equal to 100% by weight of the said diamide composition and with a) and b) being miscible as a blend.

1. A composition based on fatty acid diamide comprising:
a) from 92% to 100% by weight of one or more fatty acid diamides, the said diamide(s) being treated in situ by a neutralizing agent to reduce the residual amine content in the said one or more fatty acid diamides to a residual amine number, expressed in mg KOH/g, which remains less than 0.5, b) optionally, from 1% to 8% by weight of at least one amorphous or semi crystalline oligomer with a Tg of greater than 60° C.,provided that, if said oligomer b) is present, the sum of the % by weight a)+b) is equal to 100% by weight of said diamide-based composition, and that a) and b) are miscible as a blend in the molten state, and that the said oligomer b) is devoid of any nucleophilic group or structure.
