Folded Chain Lamellar Crystal Self-Decoration of Extended Chain Crystals of a Random Terpolymer Main Chain Liquid Crystal Polymer

Abstract Surface melting of extended chain crystals of a flexible segment containing liquid crystal polymer followed by quenching is shown to result in the epitaxial crystallization thereon of folded chain lamellae, i.e. self decoration. It is proposed that the initial extended chain lamellae form by chain folding in the mesomorphic state followed by rapid chain extension by the “chain sliding mechanism”, the same mechanism that has been in the literature for the proposed similar crystallization of polyethylene under anabaric conditions.
