Abstract This presentation will show the synthesis of hollow and microporous organic polymers (HMOPs) using zeolitic imidazolate framework (ZIF-8) as a template. Sulfonic groups were incorporated into HMOPs via a post synthetic method. The final material, HMOP-SO3H is applied as antifouling seeds and efficient catalyst activator for polyketone synthesis. Polyketones are thermoplastic polymers which have been produced in methanol using CO, ethylene, and Pd catalysts. One of the main obstacles for managing continuous synthetic process of polyketone is the reactor fouling that raises synthetic costs and reduces the bulk density of polymers. To solve an antifouling problem, seed materials have been added to the reaction media. The HMOP-SO3H showed high dispersibility in organic solvent and excellent performance as heterogeneous seed materials in polyketone synthesis. Through screening the synthetic conditions, it was found that a very small amount of HMOP-SO3H showed successful antifouling performance, compared to the conditions of industrial cases. According to PXRD analysis, the polyketones prepared by HMOP-SO3H showed α phase more dominantly than β phase, which means that polyketones are crystallize more gradually by seed mediated polymerization.
