Title:
NOVEL COMPOUND, CROSSLINKING AGENT AND CROSSLINKED FLUOROELASTOMER
Document Type and Number:
WIPO Patent Application WO/2021/125347
Kind Code:
A1
Abstract:
The present invention provides a crosslinking agent which is capable of improving the high-temperature steam resistance of a crosslinked fluoroelastomer; and a crosslinked fluoroelastomer which has improved high-temperature steam resistance. The present invention provides a compound which has a structure represented by formula (1). (In the formula, each of R1 to R6 represents a hydrogen atom, a substituent or a leaving group, provided that two or more moieties among the R1 to R6 moieties represent leaving groups; each of Ra to Rc represents a hydrogen atom or a substituent; and n represents an integer from 2 to 5.)
