The crystallization behavior of poly(oxyethylene)-b-poly(oxybutylene) block copolymers with different compositions, morphologies and architectures (E m B n diblock copolymers and E m B n E m , B n E m B n triblock copolymers) were investigated and the effect of volume fraction and architecture on th
## Abstract Lowβfrequency Raman spectra are reported for monodisperse methyleneβoxyethyleneβmethylene triblock oligomers. Assignments are made to the longitudinal acoustical modes (LAMs) of the oxyethylene block and the methylene block. The results for LAMβ1 can be modeled by the vibrations of rods
