Polymers and processes for synthesizing the polymers from .alpha.,.beta.- unsaturated lactones, particularly 2(5H)-furanone, and amines with side chains. The polymers are used as hydrogels, as polymers that can bind metals and form complexes that are soluble in organic solvents, as polymers useful as flocculants in water purification, as polymers useful on non-fouling surfaces for biofilm suppression, polymers for use on non-thrombogenic surfaces, and polymers with uses as thin conductive films for microchips and other electronic devices. The process is a polymerization reaction involving the cyclic-.alpha.,.beta.-unsaturated lactone and a primary amine or primary ammonium compound.

L'invention concerne des polymères et procédés de synthèse des polymères à partir de lactones alpha , beta insaturées, notamment de furanone 2(5H) et d'amines à chaînes latérales. On utilise les polymères comme hydrogels, comme polymères capables de lier des métaux et de former des complexes solubles dans des solvants organiques, comme polymères s'utilisant comme floculants de purification d'eau, comme polymères s'utilisant sur des surfaces anti-encrassement pour l'élimination de films biologiques, comme polymères destinés à s'utiliser sur des surfaces non thrombogènes et comme polymères s'utilisant comme films conducteurs minces pour des micropuces et d'autres dispositifs électroniques. Le procédé consiste en une réaction de polymérisation comprenant la lactone alpha , beta insaturée cyclique et une amine primaire ou un composé d'ammonium primaire.
