Formation of the phase structure of polymer systems of ethylene copolymers–[3-(2-aminoethylamino)propyl]trimethoxysilane

The Dependence of the Modified Bitumen Properties on the Amount of Vinyl Acetate in the Sevilen Composition

“…Thus, when the vinyl acetate concentration increases in the EVA composition, the binder becomes more plastic. This effect is logical, since it is known that a polymer with a high content of vinyl acetate groups exhibits elastomer properties more than a thermoplastic [17,18,20].…”

“…For copolymers with a content of more than 20% vinyl acetate groups, the molecules are fringed micelles. In the area of high content of vinyl acetate units, copolymers form a Gaussian coil [20], that contributes to an increase of the modified binder extensibility.…”

“…From the works of Russian and foreign authors [6,7,[10][11][12][13][14][15][16][17][18], the sevilen positive effect on the bitumen and asphalt concrete characteristics is known, however, these studies were limited by the use of 1-2 polymer compositions [10,20], and in some works the vinyl acetate amount is completely not specified [11,18].…”

Improving the Bitumen Quality through the Comprehensive Polymer-Based Modification

“…Unlike thermoplastic, when exposed to tension stresses, these materials can stretch severalfold, and after the force is not applied anymore, they recover their initial size. This can be explained by the fact that rubber macromolecules are rolled into a spiral [19].…”
