摘要
Process for preparing an uncrosslinked bitumen-polymer composition comprising: a) preparing an uncrosslinked bitumen-polymer composition (BPa) comprising at least one uncrosslinked bitumen-polymer base and an additive of general formula (I) R1 - (COOH) z in which R1 is a hydrocarbon chain, linear or branched, saturated or unsaturated comprising from 4 to 68 carbon atoms, and z an integer varying from 1 to 4, b) the dilution of the bitumen-polymer composition not crosslinked (BPa) with at least one bitumen base. Bitumen-polymer composition obtained by this process and its uses, in particular for the manufacture of coated materials.
