A radiation curable temporary laminating adhesive composition for use in temperature applications at 150&#xb0; C. or greater, and typically at 200&#xb0; C. or greater, comprises (A) a hydrogenated polybutadiene diacrylate; (B) a radical photoinitiator; and (C) a diluent.

Radiation curable temporary laminating adhesive for use in high temperature applications

Versatile synthetic methodology has been established for the production of a variety of siloxane and silane-containing radial epoxy resins and intermediates. This chemical approach has been exploited to obtain a variety of hybrid organic/inorganic materials that can be described as epoxysiloxane or epoxysilane radial copolymers. The methodology can be used to access reactive, hydrophobic Si-containing resins with good organic compatibility that are structurally distinct from epoxy-functional siloxanes/silanes known in the prior art. These hybrid radial epoxy resins may be utilized for a variety of adhesive and coating applications including radiation and thermally curable sealants, encapsulants and adhesives.

Epoxy-functional hybrid copolymers

Glycidyl esters are prepared to have low chlorine, chloride, sodium and potassium contamination and a thixotropic index greater than 3.0 by a process that comprises reacting carboxylic mono- or dimer acids with glycidyl alcohols in a molar ratio of 1 to (0.9-4.0) using carbodiimide as the acylating agent and a pyridine-type catalyst. The pyridine-type catalyst is removed by strongly acidic ion exchange resin.
