Abstract
The present application relates to a phthalonitrile resin, a polymerizable composition, a prepolymer, a composite, and a preparation method and use thereof. The present application can provide phthalonitrile, and a polymerizable composition and prepolymer using the same, which can have excellent curability, exhibit a suitable processing temperature and a wide window process, and form a composite having excellent physical properties.
Claims18
A phthalonitrile resin comprising a polymerized unit derived from a compound of Formula 1 below:
- wherein, R1 to R10 are each independently hydrogen, an alkyl group, an alkoxy group, an aryl group or a substituent of Formula 2 below, provided that at least one of R1 to R5 is a substituent of Formula 2 below and at least one of R6 to R10 is a substituent of Formula 2 below, and X is an alkylene group or an alkylidene group,
- wherein, L is an alkylene group, an alkylidene group, an oxygen atom or a sulfur atom.
A polymerizable composition comprising a compound of Formula 1 below and a curing agent:
- wherein, R1 to R10 are each independently hydrogen, an alkyl group, an alkoxy group, an aryl group or a substituent of Formula 2 below, provided that at least one of R1 to R5 is a substituent of Formula 2 below and at least one of R6 to R10 is a substituent of Formula 2 below, and X is an alkylene group or an alkylidene group,
- wherein, L is an alkylene group, an alkylidene group, an oxygen atom or a sulfur atom.
