Effects of crystal structure of poly(β-propiolactone) blocks on the cooperative crystallization of a polyethylene-block-poly(β-propiolactone) diblock copolymer

The crystalline morphology of a double crystalline polyethylene-block-poly(β-propiolactone) diblock copolymer (PE-b-PPL) was examined using synchrotron small-angle X-ray scattering (SR-SAXS), where the PPL block crystallized into δ- or β-form according to the thermal history during sample preparatio...
