PCT No. PCT/FR94/00323 Sec. 371 Date Nov. 13, 1995 Sec. 102(e) Date Nov. 13, 1995 PCT Filed Mar. 24, 1994 PCT Pub. No. WO94/22958 PCT Pub. Date Oct. 13, 1994Non-gellable, high temperature storage-stable bitumen/polymer compositions are provided and which are produced by stirring a sulphur-cross-linkable elastomer, an antigelling adjuvant and a sulphur-donating coupling agent into a bitumen or bitumen mixture at 100 DEG -230 DEG C. The antigelling adjuvant has the formula R-X wherein R is a C2-50 monovalent organic radical and X is a carboxylic acid, sulfonic acid or phosphoric acid group. The bitumen-polymer compositions may be used directly or in diluted form in a bitumen or bitumen mixture to form bitumen/polymer binders for producing road surfaces, coating materials or sealing materials. |
