LIGHT-TRANSFORMING POLYMER MATERIAL Russian patent published in 2000 - IPC

FIELD: polymer materials. SUBSTANCE: material is based on polyethylene, includes optically active additive based on yttrium-europium oxisulfide with general formula Y_2-xEu_xO₂S_1±0,2 where x=0.001-0.1 (0.05-0.5%), and is distinguished by additionally containing 0.1-1.0% of organic photoactive filler based on amino-derivatives of butanedioic acid, weight ratio of inorganic photoactive additive to organic photoactive filler ranging from 1:2 to 2:1. EFFECT: increased wear resistance, mechanical strength, and radiation resistance persisting for 2-3 agricultural seasons, and also increased (by 20-30%) reproduction capacity. 2 cl, 2 tbl, 8 ex
