Thiol-Cured Elastomeric Epoxy Resins |
| 摘要 |
Elastomers are formed by curing a reaction mixture that includes an 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. |

1. A process for forming an elastomeric polymer, a) forming a reaction mixture containing 1) at least one polyepoxide-terminated polyether having a linear or branched polyether chain that has a molecular weight of at least 2000 and an epoxide equivalent weight of at least 400, which polyepoxide-terminated polyether is formed by the reaction of a polyether that has epoxy-reactive groups and an average molecular weight of at least 3,500 with an epoxy resin, 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 and b) curing the reaction mixture to form the polymeric elastomer. |
