摘要：

Poly(butyl methacrylate) gels with photolabile cross-linked acyloxime units were prepared. The acyloxime moieties are scissioned on exposure to UV radiation, the cross-links decouple, and the solid material is thereby solubilized. The quantum yield of cross-link decoupling is about θ = 0.03. The physicochemical consequences of cross-link decoupling are investigated. © 1990, American Chemical Society. All rights reserved.
