Abstract: The novel feature in the preparation of microencapsulated polymers by polymerisation of microencapsulated monomer droplets suspended in an aqueous phase is that the aqueous phase contains a polymerisation inhibitor. The monomer droplets preferably contain styrene and a crosslinker, and the polymerisation inhibitor is inorganic or organic. Preferably the inhibitor is used at 10-1000 ppm based on total weight of aqueous + inhibitor and is an N compound, phosphorous acid salt, S compound, peroxy compound, phenolic compound, unsaturated lactone or hydroxyketone.

Abstract: The invention relates to a process for producing weakly basic anionic exchanger, based on cross-linked vinyl aromatic polymers by making them react with N-chlormethylphtalimide, by decomposing at high temperature the resulted product in the presence of methylamine into N,N'-dimetylphtalimide and weakly basic anionic exchangers, containing primary aminomethyl groups linked to the cycle and further treating said N,N'-dimethylphtalimide in order to convert it into the initial N-chlormethylphtalimide
