HYDROPHILIC POLYMER ARTICLE, METHOD OF PRODUCTION AND CAT'S EYE ARTICLE WITH USE OF HYDROPHILIC ARTICLE Russian patent published in 1999 - IPC

FIELD: hydrophilic polymer articles. SUBSTANCE: hydrophilic polymer article contains polymer sheet with particles of metal oxide dispersed in polymer material. Polymer sheet has the first main surface and internal region distinguished by the fact that metal-carbon atom quantity ratio on the first main surface of polymer sheet is higher than that in its internal region. In this case, particles of metal oxide are taken in amount from 5 to 90 wt.%. Invention also presents description of method of production of hydrophilic polymer article and cat's eye article. EFFECT: new method of production of article possessing high effect of water spreading. 11 cl, 10 tbl, 5 ex
