Abstract:
We present an experimental piece of evidence of the excess small-angle-scattering in a nearly symmetric diblock copolymer. This phenomenon is observed only in the two-phase coexistence region of the ordered and disordered phases near the order-disorder transition temperature, using the ultra-small-angle x-ray scattering method. This excess scattering is found to be caused by the difference of the density between the ordered and disordered phases in the coexistence region.

Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
