SULFUR-CONTAINING POLY(ALKENYL) ETHERS, PREPOLYMERS INCORPORATING SULFUR-CONTAINING POLY(ALKENYL) ETHERS, AND USES THEREOF

摘要

Sulfur-containing poly(alkenyl) ethers can be incorporated into the backbone of polythioether prepolymers and can be used as curing agents in thiol-terminated polythioether prepolymer compositions. Cured sealants prepared using compositions containing sulfur-containing poly(alkenyl) ether-containing polythioether prepolymers and/or sulfur-containing poly(alkenyl) ether curing agents exhibit improved physical properties suitable for use in aerospace sealant applications.
