Free radical initiated polymerisation method using an anionic surfactant as a stablizing agent

摘要

A method of free radical initiated addition polymerization of at least one ethylenically unsaturated monomer in which the dispersed phase is stabilized by a surfactant including at least one anionic surfactant of the formula (I) R1-(OA)n-X or a salt thereof wherein R1 is a C16-22 hydrocarbyl group including two ethylenic double bonds; OA is an oxyalkylene group; n is 2 to 60 and X is a group including at lest one acidic H atom. The polymer obtained is useful as a binder or film former in coatings, water borne adhesives or inks or as a binder for non woven fabrics, concrete and cement additives.
