Chemical resistance of core-shell particles (PS/PMMA) polymerized by seeded suspension
Polímeros, 2017 Core-shell particles were produced on seeded suspension polymerization by using polystyrene (PS) as polymer core, or seed, and methyl methacrylate (MMA) as the shell forming monomer.

Modelling and Simulation of a Batch Poly(Vinyl Chloride) Reactor
Chemical Engineering Transactions, 2013 A population balance model for batch suspension polymerization of vinyl chloride is presented. Break up into two equal volumes of droplets, binary aggregation and random mass exchanges between the colliding droplets are assumed, while the kinetic data of

Suspension Polymerization Processes [PDF]
Chemical Engineering & Technology, 2010 AbstractIndustrial suspension polymerization usually proceeds by a free‐radical mechanism to produce polymer beads. The size distribution of the polymer beads is often similar to that of the polymerizing drops in the reactor. That distribution is determined by the operating mechanisms of drop breakage and drop coalescence.

Polymerization of tetrazine-substituted diacetylenes as aggregates in suspension
Photochemical & Photobiological Sciences, 2023 Polydiacetylenes (PDAs) are conjugated polymers that have been widely exploited for their chromogenic and fluorogenic transitions upon exposure to external stimuli and biomolecules of interest. Herein, we propose a comparative study of the polymerization dynamics of two diacetylene derivatives, TzDA1 and TzDA2, in the form of aggregates in suspension ...
