概要 The lamellar morphol. in banded spherulites of poly(epsilon-caprolactone) blended with an amorphous polymer, poly(vinyl butyral), was investigated by three-dimensional transmission electron tomog. It showed a local lamellar twist on a smaller scale than the band spacing by 2 orders of magnitude. It also indicated wavy lamellae and frequent variation in the direction of the lamellar plane. All these results indicated an S-profiled lamellar structure; i.e., the cross section perpendicular to the lamellar growth direction was S-shaped. S-profiled lamellae show these structures when they are sliced at a certain angle to the lamellar surface direction. Lamellar branching was also obsd., but no screw dislocations that led to the formation of extinction rings were obsd. in this work.
