Embodiment 1

[0169] Curable polythioether compositions were prepared as follows. To a 40 mL opaque amber glass jar was added 5.000 grams of DMDO, 3.1067 grams of DVE, 1.2946 grams of TAC, 0.0940 grams of I-819 and 0.0005 grams of D177. The vial was then sealed and placed on a laboratory roller mill at 21 °C until the solids dissolved.

Embodiment 2

[0176] To a 40 mL amber glass vial was added 10.000 grams of oligomer 1, 0.5700 grams of TAC, 0.1057 grams of I-819 and 0.0005 grams of D177. The vial was then sealed and placed on a laboratory speed mixer and run at 2000 rpm for 1 minute.

Abstract

A curable composition having a polythiol; at least one unsaturated compound comprising more than one carbon-carbon double bond, carbon-carbon triple bond, or a combination thereof; and a dye compoundrepresented by formula (I). A crosslinked composition prepared from the curable composition, a method of making an at least partially crosslinked network, a method for indicating curing in a curable composition, and a method of stabilizing a curable composition comprising a polythiol and at least one unsaturated compound comprising more than one carbon-carbon double bond, carbon-carbon triple bond, or a combination thereof are also disclosed. Z is not reactive with the polythiol or unsaturated compound.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 185,775, filed June 29, 2015, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] Inclusion of a dye in the curing agent or catalyst composition may be useful, for example, when the curing agent or catalyst must be mixed with the curable resin prior to placing and curing the resin. Dyes may be useful, for example, to indicate cure or the catalyst is uniformly mixed with the curable resin. Peroxide and dye formulations are also known in which the color disappears when the peroxide is used to generate free radicals during curing of the curable resin. See, eg, Japanese Patent Application Publication SHO 59-120612 published Jul. 21, 1984, and US Patent Application Publication 2006 / 0202158 (Chen et al.). While many methods exist to determine the degree of cure in a curing system, most methods require...
