4. Conclusion
In this article, we synthesized a simple benzene-centered
trifunctional activator of N,N0,N00-trimesoyltricaprolactam. Subsequently,
star-branched polyamide 6 was prepared via e-caprolactam
magnesium bromide catalyzed anionic ring-opening
polymerization of e-caprolactam in the presence of this activator.
In contrast to its linear counterparts, the resultant star-branched
polyamide 6 showed smaller relative viscosity, decreased melting
temperature and lower crystallinity. The specific properties
demonstrated the existence of a star-branched structure and
provided potential advantages in engineering applications.
