Abstract
Cationic chemically modified asphalts having utility for road construction, repair and maintenance as well as coating for various substrates, including cementitious substrates, glass and metal are provided. These asphalts are the product produced by reacting an acrylamide, asphalt, a vinyl aromatic monomer and a rubbery polymer.
Claims21
As a composition of matter, the product produced by reacting an acrylamide, asphalt, a vinyl aromatic monomer and a rubbery polymer.
A chemically modified asphalt reaction product produced by charging into a reactor an acrylamide having a double bond, asphalt, a vinyl aromatic monomer, and a rubbery polymer which is a homopolymer of a diene or a copolymer of a diene and an olefinically unsaturated monomer and heating the materials at an elevated temperature for several hours so as to produce said reaction product.
A method comprising charging into a reactor an acrylamide compound having a double bond, asphalt, a vinyl aromatic monomer, and a rubbery polymer which is a homopolymer of a diene or a copolymer of a diene and an olefinically unsaturated monomer and heating the materials at an elevated temperature for several hours.
