Abstract
A method of producing glass strands, the method comprising coating glass strands with a heat-polymerizable composition constituted by a solution with a solvent content of less than 5% by weight and a viscosity of less than 400 cP, the solution comprising a basic structure which can be polymerized or cross-linked thermally, the structure comprising at least 60% by weight of one or more components with molecular weights of less than 750, having at least one acrylic and/or methacrylic and/or vinyl ether and/or N-vinylamide and/or N-vinyllactam function, the proportion of polyfunctional components within these components being at least 45% by weight of these components, so as to produce glass strands coated with a non-polymerized, heat-polymerizable composition; the glass strands produced, as well as to composites produced from the strands.
