A comprehensive investigation into “controlled/living” chain growth crosslinking copolymerization including a back to basics modeling

摘要: The mainstay of this description is a modeling "controlled/living" chain growth crosslinking copolymerization (C/L CC) that based on simple equivalent kinetic scheme, resulting from assumptions consistent with an ideal C/L behavior. Analytical expressions the double bond concentration according to reaction parameters are derived corresponding set differential equations, and consideration respective values rate constants enables one forecast morphology branched polymers by CC. scheme then enriched necessary distinction between intramolecular (cyclization) intermolecular which contribute formation three-dimensional structures increase molar masses, respectively. This leads key-equation governing CC, can be exploited in two ways. Its implicit integration coupled semi-empiric methodology gives easy access all characteristic magnitudes products at complete conversion bonds. An alternative approach implying supplementary local effects its numerical resolution. Modeled trends predicted successfully compared experimental data relate xanthate-mediated radical Specific reasons dispersity related mechanism CC also discussed.
