APPLICATION OF WAXES IN A CREATED BITUMINO-POLYMER COMPOSITION FOR IMPROVING ITS RESISTANCE TO CHEMICAL EXPOSURE AND A SEWED BITUMINO-POLYMER COMPOSITION CONTAINING WAXES

摘要

1. The use of 2 to 6 wt.% Fischer-Tropsch waxes in relation to the mass of the crosslinked bitumen-polymer composition in a cross-linked bitumen-polymer composition containing a cross-linked copolymer of an aromatic monovinyl hydrocarbon and a diene with conjugated double bonds, to improve the stability of the cross-linked bitumen-polymer composition to aggressive chemical agents. 2. Use according to claim 1, wherein the crosslinked copolymer of an aromatic monovinyl hydrocarbon and a conjugated diene is a crosslinked copolymer of styrene and butadiene. The use according to claim 1, in which the copolymer of an aromatic monovinyl hydrocarbon and a diene with conjugated double bonds, in particular styrene and butadiene, has a content of 1,2 units of a double bond formed from a diene with conjugated double bonds, which ranges from 5 to 50 wt. % based on the total weight of the conjugated diene units, preferably 15% to 30%, even more preferably 18% to 25%, even more preferably 18% to 23%, or 20% to 25%. 4. The use according to claim 3, wherein the content of the 1,2 units of the double bond formed from the conjugated diene, which is from 10 to 40 wt.% With respect to the total weight of the units of the conjugated diene. Use according to claim 1, wherein a copolymer of an aromatic monovinyl hydrocarbon and a conjugated diene is combined with a crosslinking agent. Use according to claim 5, wherein the crosslinking agent comprises a gray color. Use according to claim 5, in which the crosslinking agent is selected from compounds of the general formula HS-R-SH, where R is saturated or unsaturated, normal
