The effect of surface roughness on the adhesive properties of statistical, uncrosslinked butyl acrylate–methyl acrylate copolymers with different molecular weights (M w =54000, 192000, and 600000g/mol) has been investigated using a combination of probe tack test and simultaneous video-optical imaging. Steel probes with different average surface roughnesses (R a =2.9, 41.2, and 291...
