    Abstract: The invention pertains to a method of making urea-containing particles wherein with a lower degree of cooling, high mechanical strengths are obtained. The method comprises the steps of (a) providing a first polymer 10 layer; (b) feeding urea droplets onto said first polymer layer, (c) cooling the droplets provided on the first polymer layer to a temperature between 55º C and 120º C; (d) applying a second polymer layer onto the first polymer layer comprising the droplets so as to form encapsulated urea droplets; and (e) separating the encapsulated urea droplets.

    Abstract: Batch reactor comprising a reaction vessel that is longitudinally shaped and has a side wall that encloses a reaction space of the reaction vessel. The reaction vessel is arranged for holding in the reaction space a reaction mixture that comprises polyamide and/or a liquid monomer composition. The reaction further has a bottom wall that further encloses the reaction space. The side wall extends in a longitudinal direction of the reaction vessel that is, in use, directed upwards. The batch reactor has an outer heat exchanger for exchanging heat with the reaction space for enabling a polymerization reaction. The outer heat exchanger covers at least a part of the side wall. The batch reactor comprises an inner heat exchanger that is provided in the reaction space. The inner heat exchanger is, at least partly, surrounded by the outer heat exchanger. The batch reactor comprises an agitator for transporting the reaction mixture.
