Title:
STAR NYLON, ITS PRODUCTION, TETRASUBSTITUTED CARBOXYLIC ACID, AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH069777
Kind Code:
A
Abstract:
PURPOSE: To produce a star nylon having a low melt viscosity and excellent mechanical properties.
CONSTITUTION: A star nylon which has at least three nylon polymer chains each of which has been formed using, as the polymn. initiation site, one of at least three polymn. initiation groups attached to carbon atoms at positions separated apart from each other by at least one carbon atom on an arom. ring of an arom. compd. The nylon is produced by homogeneously mixing the arom. compd. with a nylon monomer melt and polymerizing the monomer. Thus, the nylon is obtd. in which no intramolecular cross-linking is formed and intermolecular hydrogen bonding is satisfactorily formed and which has a low melt viscosity and excellent mechanical properties.
