Abstract:

PCT No. PCT/FR96/01614 Sec. 371 Date Aug. 20, 1997 Sec. 102(e) Date Aug. 20, 1997 PCT Filed Oct. 16, 1998 PCT Pub. No. WO97/14754 PCT Pub. Date Apr. 24, 1997Functionalized elastomer/bitumen compositions with a broad plasticity range are produced by contacting a bitumen or bitumen mixture with an elastomer, a functionalizing agent and optionally a peroxide compound at 100 DEG -230 DEG C. under stirring conditions. The funtionalizing agent is a thiolcarboxylic acid having 3 or more carbon atoms, a thiolcarboxylic acid ester and specifically a disulphide having carboxylic groupings or carboxylic esters. The compositions may be used either directly or in diluted form to produce bitumous binders for making road surfacings, coated materials and sealing coatings.
