Abstract
An aqueous dispersion of 1 - 300 parts by weight of an olefin-acrylate copolymer, said olefin having 3 to 20 carbon atoms, in 100 parts by weight of water, the dispersion optionally containing a surface active agent in a proportion of 0.1 to 20 parts by weight per 100 parts by weight of the copolymer, in which dispersion the copolymer forms substantially the dispersed phase and the water forms the continuous phase. Said dispersion can be used in paints, fiber-treating agents, paper-treating agents, leather-treating agents and adhesives, and forms a film having excellent resistance to alkali, water, weathering and heat. The above copolymer is preferably an alternating copolymer although it may be a random copolymer.
