Zusammenfassung:	To provide a process for forming an elastic polymer relating to elastic epoxy resins.SOLUTION: Elastomers are formed by curing a reaction mixture that includes 1) a polyepoxide-terminated polyether having a linear or branched polyether chain that has a molecular weight of at least 2000, at least two epoxide groups that has an epoxide equivalent weight of at least 400, 2) a curing agent containing at least one polythiol compound having at least two thiol groups and an equivalent weight per thiol group of up to 500, and 3) at least one base catalyst.SELECTED DRAWING: None 【課題】弾性エポキシ樹脂に関する弾性ポリマーを形成するためのプロセス。【解決手段】エラストマーは、１）少なくとも２０００の分子量、少なくとも４００のエポキシド等価重量を有する少なくとも２つのエポキシド基を有する直鎖または分枝ポリエーテル鎖を有するポリエポキシド末端ポリエーテル、２）少なくとも２つのチオール基および最大５００のチオール基当たり等価重量を有する少なくとも１つのポリチオール化合物を含有する硬化剤、ならびに３）少なくとも１つの塩基触媒、を含む反応混合物を硬化させることによって形成される。【選択図】なし
