Description: A replica of a 1:3 blend of linear with lightly branched (BPE has 26 branched per 1000 backbone carbon atoms) polyethylenes after quenching from a mixed melt. The lamellae are of a single type, all of the same thickness. In this case the lamellae are arranged in the familiar banded spherulites.
