ABSTRACT OF THE DISCLOSURE Stable, free-flowing dispersions in organic liquids of rubbers in the form of discrete particles having an average diameter of from 100 to 3000 nm which contain: A - as rubber, from 1 to 20% by weight, based on the total dispersion, of a crosslinked diene rubber; B - from 0 to 20% by weight, based on the total dispersion, of water in the form of a water-in-oil emulsion; C - as the continuous organic phase, from 99 to 66% by weight, based on the total dispersion, of a) C1-C10 alkyl acrylates or alkyl methacrylates, methyl methacrylate, ethyl acrylate or n-hexyl acrylate; or b) a mixture of from 85 to 50 by weight of styrene or .alpha.-methyl styrene and from 15 to 50% by weight of acrylonitrile, methacrylonitrile or C1-C6 alkyl acrylates or alkyl methacrylates, methyl methacrylate, ethyl acrylate, n-hexyl acrylate; or c) a mixture of from 85 to 50% by weight of a C1-C10 alkyl acrylate or alkyl methacrylate and from 15 to 50% by weight of acrylonitrile, methacrylonitrile or styrene; up to 60% by weight of a liquid hydrocarbon can be added to and mixed with a), b), and c), and a process for producing said stable dispersions which include discrete microgel particles of rubber in organic liquid and which may be polymerized, for example by means of radical initiators or redox initiators, and hardened at room temperatures of from 0 to 150°C, and when the dispersions additionally contain reinforcing fillers, pigments and the like, they may be used for the production of impact-resistance coatings or, for example, as cast resins having specialised properties, such as high resistance to ageing.
