The present disclosure generally related to photopolymerizable liquid compositions containing hybridized graft copolymers, reactive diluents and optionally oligomers, photoinitiators, colorants and other additives.

Initiator/mediator chemistry for latent imaging polymers for volume Bragg gratings is provided. Light mediated chemistry including the use of nitroxides allows a first step imaging to occur, where a light induced pattern is recorded in the material, without the grating being apparent. A second bleaching/developing step completes the curing process and reveals the grating.

The invention relates to an elastic material having high rebound resilience, which is an energy-cured material obtained from a composition comprising a specific urethane (meth)acrylate comprising oxybutylene units.

Curable compositions comprising a urethane multifunctional (meth)acrylate, a photo initiator system, a moisture-cure initiator, and an oligomer, where the oligomer is represented by the formula (I) where each X.sup.1 is independently alkylene; each X.sup.2 is independently alkylene, polyether, polyester, or polyurethane; R.sup.1 is a (meth)acrylate; R.sup.2 is urethane or isocyanate; and R.sup.3 alkylene (meth)acrylate, polyester (meth)acrylate, polyether, polyester, polyurethane, or nothing, and where the ratio of (meth)acrylate to isocyanate in the oligomer is 1:1 to 1:2. Methods of making curable compositions, methods of sealing a substrate, and methods of adhering two substrates are provided.
