    摘要: Non-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.degree.-230.degree. C. The antigelling adjuvant has the formula R--X wherein R is a C.sub.2-50 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.

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.

    摘要: Bitumen/polymer compositions are produced by contacting, between 100.degree. C. and 230.degree. C., under agitation, one bitumen or a mixture of bitumens with at least one olefinic polymer bearing epoxy or COOH groupings, then by incorporating in the product, an acid additive while the whole mixture is agitated at a range between 100.degree. C. and 230.degree. C. for at least 10 minutes. The product, which is subjected to treatment by the acid additive may still contain one or several additional polymers, for instance of the elastomer type cross-linkable with sulphur, and even be subjected to sulphur cross-linking before treatment. The bitumen/polymer compositions are useful directly or after dilution, to form binders for carrying out surfacing operations.
