    摘要： Curable compositions include at least one monomer compound having both (meth)acrylic ester functionality and an allylic phenyl ether functional group on the same molecule, the allylic phenyl ether functional group having at least one unsubstituted position on the phenyl ring which is ortho or para to the allylic ether group, and a free radical catalyst system. The composition may also includes a latent thermally activated acid generator. Claisen Rearrangement of radically polymerized polymers produced from the compositions may be induced at temperatures of about 100° C. or more to give crosslinked products of improved thermal resistance. Novel monomers which may be used in such compositions are characterized by formulas I and II: where R1 is H or methyl; R2 is a direct bond, a group of the formula —NCnH2n-, or a group of the formula —(OCnH2n—)m— which when taken with the phenyl group to which it is attached forms a phenyl ether; n is 1-4 and m is 1-10; R3 is —CH2CH═CH2, —CH2C(CH3)═CH2, —CH2CH═CH(CH3), —CH2C(CH3)═CH(CH3), —CH2CH═C(CH3)2 or —CH2 CH═CH(C6H5); and R4 is a divalent allylic group, and wherein the compound is optionally substituted on a phenyl group thereof by an alkyl, alkoxy or halo group, provided that relative to the respective —OR3 or —OR4O — groups, at least one unsubstituted ortho or para position remains on an adjacent phenyl ring.
