Title:
RADICAL POLYMERIZATION CONTROL AGENT AND RADICAL POLYMERIZATION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/009157
Kind Code:
A1
Abstract:
[Problem] Conventional polymerization inhibitors are used to capture radicals generated, for example, during storage of a radical polymerizable compound, thus allowing the radical polymerizable compound to be safely handled. However, the polymerization inhibitors constitute unnecessary additives when radical polymerization of the radical polymerizable compound is actually being effected, and are preferably removed before the radical polymerization. The purpose of the present invention is to eliminate this inconvenient removal step. [Solution] This radical polymerization control agent is contained in a radical polymerizable composition, and serves as a radical polymerization inhibitor when, for example, stored in darkness. When polymerization is initiated under irradiation with light of a specific wavelength, the radical polymerization control agent loses the radical polymerization inhibitory effect. This makes it possible to easily initiate polymerization of a radical polymerizable compound without increasing the amount of a radical polymerization initiator. Namely, the radical polymerization control agent is a compound effective in inhibiting radical polymerization of a radical polymerizable compound and characterized by losing the radical polymerization inhibitory effect under irradiation with beams including light within the wavelength range of 300 nm to 500 nm.
