the specification discloses noncracking permanent adhesives which utilize mixtures of phenolic resins and methacrylate resins having a mw greater than about 100 , 000 and preferably about 400 , 000 bonding plasticized vinyl resin coverings , e . g ., pvc , to hard polymeric substrate surfaces such as abs , etc . also , it is preferable that the vinyl resin covering contain plasticizers which are no more than limited in compatibility with the adhesive . it is theorized that the adhesive mixture prevents migration of plasticizer from the plasticizer - containing vinyl resin covering into the adhesive and eventually into the polymeric substrate .
