Abstract

Provided is a radically polymerizable resin which has a low viscosity, has excellent workability, and is rapidly cured upon application of heat and/or light to form a cured product having excellent flexibility and thermal stability. The radically polymerizable resin composition is obtained by cationic polymerization of an oxetane-ring-containing (meth)acrylic ester compound represented by following Formula (1) alone or in combination with another cationically polymerizable compound. In Formula (1), R¹ represents hydrogen atom or methyl group; R² represents hydrogen atom or an alkyl group; and “A” represents a linear or branched chain alkylene group having 4 to 20 carbon atoms.

Claims

1. A radically polymerizable resin obtained through cationic polymerization of an oxetane-ring-containing (meth)acrylic ester compound alone or in combination with another cationically polymerizable compound, the oxetane-ring-containing (meth)acrylic ester compound being represented by following Formula (1):

2. The radically polymerizable resin according to claim 1, wherein the other cationically polymerizable compound is a compound having only one functional group selected from the group consisting of oxetane ring, epoxy ring, vinyl ether group, and a vinylaryl group per molecule.

3. A radically polymerizable resin composition comprising the radically polymerizable resin of claim 1 as a radically polymerizable compound.

4. The radically polymerizable resin composition according to claim 3, further comprising another radically polymerizable compound than the radically polymerizable resin.

5. The radically polymerizable resin composition according to claim 4, wherein the other radically polymerizable compound than the radically polymerizable resin is a compound having one or more functional groups selected from the group consisting of (meth)acryloyl groups, (meth)acryloyloxy groups, (meth)acryloylamino groups, vinylaryl groups, vinyl ether groups, and vinyloxycarbonyl groups per molecule.

6. A cured product obtained through radical polymerization of the radically polymerizable resin composition of claim 3.

7. The cured product according to claim 6, in the form of a film.

8. The cured product according to claim 6, in the form of a fiber.
