摘要:
The invention provides an aryl sulphoxonium salt which either contains a polymerizable group in the molecule or is part of a polymeric compound. The compounds are useful as cationic photoinitiators.
摘要:
A process for the preparation of a liquid radically curable composition which comprises reacting a diisocyanate with a polyol, polythiol or polyamine having a molecular weight of at least 2000 in the presence of a monofunctional acrylate which is non-reactive with respect to isocyanates, thereby forming a polyurethane, and then reacting the polyurethane with an acrylic compound to produce a polyurethane having acrylic end groups.
摘要:
Process for curing an epoxide containing at least two epoxy groups per molecule which comprises reacting the epoxide with a carboxylic acid chloride having at least two acid chloride groups per molecule.
摘要:
A composition for priming and cleaning glass, aluminium or steel surfaces which comprises a solution in an organic solvent, optionally mixed with water, of an organosilane and a compound which generates an acid on exposure to actinic adiation.
