Formation of fibrillar crystals strongly accelerates the form II to I transformation of polybutene-1

This study finds that the form II to I transformation of isotactic polybutene-1 is greatly accelerated when fibrillar form II crystals have been induced by the shear flow, and a degree of this acceleration increases with the shear rate.

An unusual transition from point-like to fibrillar crystals in injection-molded polyethylene articles induced by lightly cross-linking and melt penetration

Recently, an unusual transition from point-like to fibrillar crystals has been realized by lightly cross-linking structure and melt penetration.
