Abstract
There is disclosed laminates containing an adhesive blend, a rubbery adhesive cement as well as a method of using said cement, and products which can be prepared from the use of said cement. The rubbery adhesive cement comprises: PA0 (A) solvent, and PA0 (B) a vulcanizable rubbery polymer blend dissolved in said solvent wherein said blend is comprised of, based on 100 parts thereof: PA0 (a) 5 to 50 parts by weight of at least one rubbery conjugated diene polymer having 25% to 55% side chain unsaturation and having a Mooney viscosity of from 80 to 150 ML4 at 100.degree. C. as measured according to ASTM D1646, and correspondingly PA0 (b) 50 to 95 parts of at least one other rubbery polymer.
