Abstract
The previously studied whiskers of poly(p-oxybenzoly) consist of the extended chain type crystals with high crystallinity. The formation mechaism of these whiskers is discussed along their morphological features at the early stages of polymerization. The model has the following steps. 1) Oligomers of low DP polymerized in solution are precipitated in the form of lamella. 2) The lamellae pile up along the long axis of the needle crystals with a spiral growth caused by the screw dislocation. 3) After that, DP increases by the trans-esterification in the interlamellar regions and the reorganization of crystals occurs. A similar formation mechanism for other morphologies obtained with different coditions is also discussed.
