The present invention relates to curable compositions which comprise (meth)acrylic monomers, ethylenically unsaturated oligomers and a specific multistage polymer additive. The additive is used as a processing aid to reduce cure shrinkage and prevent the formation of cracks during the polymerization of the composition.
本发明涉及由(甲基)
丙烯酸单体、
乙烯基不饱和低聚物和特定多级聚合物添加剂组成的可固化组合物。添加剂用作加工助剂,以减少固化收缩并防止在组合物聚合过程中形成裂缝。
