  The invention relates to use of a material containing a polymerizable monomer or oligomer, the material exhibiting desirable shrinkage compensation upon polymerization. The material contains an expansion agent having a cleaving moiety with the capacity to be cleaved or fragmented by a catalytic reaction, e.g., acid catalysis. The cleavage, by increasing the number of molecules in the material, causes expansion that compensates, at least in part, for shrinkage induced by polymerization of the monomer or oligomer. The expansion agent is capable of providing compensation such that no more than 0.4%, advantageously no more than 0.2 %, volume shrinkage per molar concentration of polymerized monomer functional groups occurs, where such compensation is performed at relatively low temperatures of less than 40°C.

  本发明涉及一种含有可聚合单体或低聚物的材料的用途，这种材料在聚合时会表现出理想的收缩补偿。该材料含有一种膨胀剂，该膨胀剂具有裂解分子，可通过催化反应（如酸催化）裂解或破碎。通过增加材料中分子的数量，裂解可导致膨胀，至少部分补偿单体或低聚物聚合引起的收缩。膨胀剂能够提供补偿，使每摩尔浓度的聚合单体官能团的体积收缩率不超过 0.4%，最好不超过 0.2%，而这种补偿是在低于 40°C 的相对低温下进行的。
