FIELD: chemistry. ^ SUBSTANCE: invention refers to making a moulded product for handling clean-room materials, intermediate products or end products, such as a container, a tray and a tool. The moulded product is made of resin compound prepared by mixing in melt cycloolefine polymer (A) 100 weight fractions chosen from the group including bicyclo[2.2.1]-2-heptene and its derivatives, tricyclo [4,3,0,12,5]-3-decene and its derivatives, and tetracyclo[4,4,0,12,5,17,10]-3-dodecene and its derivatives of vitrification temperature within 60 to 200C, and amorphous or low-crystalline elastic copolymer (B(b1)) 1 to 150 weight fractions. Copolymer (B(b1)) is polymerised from at least two monomers chosen from the group including ethylene and a-olefin with 3 to 20 carbon atoms and vitrification temperature 0C or lower. The compound contains radical polymerisation initiator 0.001 to 1 weight fractions containing peroxide, and polyfunctional compound (D) 0 to 1 weight fractions. The compound (D) has at least two radical-polymerised functional groups chosen from the group including vinyl group, allylic group, acrylic group and methacrylic group in a molecule. ^ EFFECT: clean-room moulded product is characterised with good chemical stability, heat resistance and dimensional accuracy, it prevents volatile component release in the surrounding space, has good abrasion resistance and prevents particle formation. ^ 19 cl, 1 tbl, 2 dwg, 12 ex |
