Abstract

Cette invention se rapporte à des microsphères auto-adhésives composites, qui comprennent au moins deux polymères insolubles dans l'eau, qui sont entièrement mélangés à l'intérieur des limites des microsphères polymères. La gamme des monomères et des polymères est choisie pour adapter les propriétés des microsphères auto-adhésives composites à des nécessités de performances et/ou d'applications spécifiques. Tout polymère qui peut être dissous dans un monomère solvant ou dans un mélange de monomères solvants peut être utilisé pour la préparation de ces microsphères auto-adhésives composites. Ces microsphères auto-adhésives peuvent être préparées à l'aide de la polymérisation en suspension à radicaux libres.
