FIELD: chemistry.
SUBSTANCE: maleinised tall oil-based adhesive additive contains 10-30 wt % bound maleic anhydride. The tall oil used for maleinisation contains resin and fatty acids in weight ratio of 1.0:0.6-5.0, respectively. The adhesive additive is characterised by dynamic viscosity of 0.3-1.0 Pa·s. The additive can be easily batched and has good distribution in the polymer-bitumen composition. Use of the additive does not require premixing thereof with a thermoplastic elastomer, enabling preparation of the polymer-bitumen composition in a single step.
EFFECT: polymer-bitumen composition containing an adhesive additive, characterised by high adhesion to both alkaline and acidic mineral filler.
