CARPETING WARP MANUFACTURED FROM BLOCK-COPOLYMER COMPOSITIONS Russian patent published in 1999 - IPC

FIELD: polymer materials. SUBSTANCE: new carpeting contains carpeting cloth and block-copolymer composition applied on back side of carpeting. Carpeting cloth is a thermoplastic cloth made from polypropylene, polyester, or polyamide yarn. Block copolymer composition contains (i) block copolymer containing at least two terminal vinylaromatic polymer blocks and at least one internal conjugated diene polymer block and, additionally, (ii) plasticizing nonaromatic oil in amounts of 30 to 250 wt parts per 100 wt parts of block-copolymer; and (iii) resin compatible with vinylaromatic block- polymer in amounts of 30 to 200 wt parts per 100 wt parts of block- copolymer whose melt viscosity at 150-200 C is below 500 Pa s. Divided carpeting to be reprocessed and block copolymer composition for warp are also described. EFFECT: facilitated reprocessing of carpeting. 21 cl, 2 tbl, 8 ex
