POLYMERISABLE COMPOSITIONS

Highly filled, curable compositions containing a curable liquid, e.g. methyl methacrylate; 20 to 80 % by weight of a finely divided inorganic filler of defined particle size, e.g. silica; a functionalised polymer containing a low Tg component which is sol- uble in the curable liquid, e.g. a function...

Zusammenfassung:Highly filled, curable compositions containing a curable liquid, e.g. methyl methacrylate; 20 to 80 % by weight of a finely divided inorganic filler of defined particle size, e.g. silica; a functionalised polymer containing a low Tg component which is sol- uble in the curable liquid, e.g. a functionalised vinyl aromatic/conjugated diene block copolymer; and other components which disperse the filler in the curable liquid and couple the filler to the matri x can be used to produce cured composites which show improved resistance to stress induced by thermal cycling.
