Three series of non-polar acrylic copolymers based on 2-ethyl hexyl acrylate and four series of polar copolymers based on ethyl acrylate were synthesised. Their adhesion performance was assessed by measurement of the force required to detach a probe

The pigment retention efficiency, in a model papermaking system, of anionically and cationically modified polyacrylamides was compared to that of the unmodified homopolymer. The anionic polyacrylamide is a much less efficient retention aid, especiall

The radical copolymerization of acenaphthylene has been studied with styrene, methyl methacrylate, maleic anhydride, diethyl maleate, and vinylpyrrolidone. Although acenaphthylene is readily polymerizable, unlike most 1,2-disubstituted ethylenes, it
