METHOD OF PRODUCING UV RADIATION SENSITIVE SOLID POLYMER MATERIAL Russian patent published in 2011 - IPC C08F20/06 G03C1/735 

FIELD: chemistry.

SUBSTANCE: invention relates to polymer materials which are sensitive to UV radiation, which can be used to make UV induced structures in laser devices. Described is a single-step method of producing transparent block polymer material which is sensitive to UV radiation owing to presence of a uniformly distributed gold compound therein. The method involves preparation of an initial reaction mixture by dissolving a radical polymerisation initiator, selected from organic peroxides, and a noble metal compound, selected from salts with anions AuCl₄ ^-, AuBr₄ ^-, AuF₄ ^-, Au(SCN)₄ ^- and cations of quaternary ammonium bases, for example, N-cetylpyridinium, in an acrylic monomer at room temperature in liquid state. Synthesis of the polymer takes place via radical polymerisation in the mass of degassed reaction mixture while heating to temperature higher than 25°C, but lower than the boiling point of the monomer and then holding the mixture at the given temperature for 3-30 hours.

EFFECT: simplified method enables to obtain block materials which are sensitive to UV radiation.
