Abstract: A composition is described comprising an amine-reactive material; and a polymeric catalyst comprising hydroxyl groups and tertiary amine groups. The polymeric catalyst is typically suspended or dispersed in a liquid dispersant. The liquid dispersant does not covalently bond with the tertiary amine groups. The liquid dispersant is typically a hydroxy-functional or thiol-functional. Also described is a polymer network comprising the cured composition described herein, a polymer catalyst, and catalyst dispersion; as well as methods.

Abstract: A composition includes a polythiol having more than one thiol group, a polyepoxide having more than one epoxide group, an amine catalyst, and conductive filler. The conductive filler is at least one of thermally conductive or electrically conductive. The conductive filler is present in an amount to provide a thermal conductivity of at least 0.95 W/m′K, and/or the conductive filler is present in an amount of greater than 80 percent by weight, based on the total weight of the composition. A polymer network, which can be prepared from the composition, and a method for making the polymer network are also disclosed.

Abstract: Various embodiments disclosed relate to polysulfide or polythioether sealant composition including glycol organic acid esters. The sealant composition can include a first component including a liquid that is a polysulfide, a polythioether, a copolymer thereof, or a combination thereof. The sealant composition can also include a second component that includes one or more glycol di((C1-C20)hydrocarbyl)carboxylate esters, wherein at each occurrence the (C1-C20)hydrocarbyl is independently substituted or unsubstituted. The second component can also include an oxidizing agent.
