Abstract: A process for the preparation of microcapsules comprising the steps of—preparing an oil-phase comprising a multifunctional ethylenically unsaturated monomer or oligomer wherein the water solubility of the multifunctional ethylenically unsaturated monomer or oligomer at 20° C. in deionised water is less than 2 gram/litre, —forming an oil-in-water emulsion with the oil phase, —subjecting the oil-in-water emulsion to conditions suitable to initiate interfacial polymerization at the oil-water interface using a radical initiator with a water solubility at 20° C. in deionised water which is at least 1 gram/litre.

Abstract: This invention relates to a solid object prepared using three dimensional printing. The object contains one or more agrochemicals and also a surfactant or an oil; and, for example, may be in the form of a pill, capsule or granule, and may be of lozenge profile. A solid object manufactured by three dimensional printing is a convenient way to dose and apply an agrochemical to, for example, foliage, soil or a pest.

Abstract: Nanodispersions of inorganic clays in isocyanate may be created via pre-exfoliation, delamination, or both of the clay and subsequent mixing with isocyanate. In an embodiment, such an isocyanate nanodispersion is reacted with an isocyanate-reactive material or substrate to form a polyurethane nanocomposite.

Abstract: A polymer composition, a process for its preparation and a molded article formed from the polymer composition are claimed. The polymer composition comprises (a) a base polymer that is a poly(alkyl(meth)acrylate; and (b) a rubber toughening agent selected from the group consisting of (i) copolymers of (alkyl)acrylate rubbers, (ii) copolymers of vinyl aromatic monomers with (alkyl)acrylates, (iii) copolymers of vinyl aromatic monomers with conjugated diolefins; (iv) copolymers of vinyl aromatic monomers with monoethylenically unsaturated monomers, in which the rubber toughening agent is present in the polymer composition as discrete islands substantially surrounded by the base polymer and in which islands are sub-islands of the base polymer.
