摘要
A model was developed to determine the constitution of step-growth polymers synthesized from the nonsymmetric XabX monomer and the symmetric YccY monomer under various types of mixing modes. Depending upon the inherent kinetics of the system and the modes of addition of monomers, constitution (defined by the probability, s, that two adjacent nonsymmetric monomeric units in the polymer point in the same direction) can be varied over wide ranges. Results are shown for all variations of kinetic parameters and mixing modes. More detailed molecular level structure was determined by using a Monte Carlo technique.
