Title: Polymer-modified bitumen - by forming solid soln of polymer and mixing with bitumen at raised temp
Inventor: GRIGG ROGER CHARLES
IPC: C08L95/00
Filed: 1973-09-20
Abstract: Polymer. modified bituminous material is prepd. by dissolving polymeric material in a solvent, to form a soln. which is solid at normal ambient temp. and mixing the soln. with bitumen at a temp. sufficiently high that the solution is present in liquid form. Pref. the solid is added to the bitumen in solid, finely divided form. The solid soln. pref. exhibits a m. pt. corresp. to that of the bitumen. Suitable solvents are polynuclear hydrocarbons, pref. naphthalene, and a pref. polymer material is a styrene-butadiene-styrene block copolymer. The solid soln. of the polymer is easier to mix with the bitumen than it would be to mix the polymer with the bitumen. The modified bitumen has a sharper transition pt. from plastic to solid condition when temp. is lowered than with conventional modified bitumens.
