Notes:
Poly(vinyl fluoride) polymers prepared at different polymerization temperatures have been examined in the melt, oriented, and solid state by infrared spectroscopy. Bands arising from the head-to-tail and head-to-head-tail-to-tail portions of the polymer have been isolated and assigned. The head-to-head-tail-to-tail portion of the polymer crystallizes in the head-to-tail unit cell except for a portion of the 1,2-difluorethylene units which apparently have the gauche (out-of-plane) structure. The head-to-tail portion of the polymer is nearly atactic, but is somewhat rich in syndiotactic chain structure. Bands arising from local syndiotactic order are observed.
