Resumen
ABSTRACT: A removable pressure-sensitive adhesive was obtained by free-radical
emulsion polymerization. The product is a low-viscosity copolymer from different
polar and apolar acrylic monomers consisting of microspheres of about 1 µm diameter. 2-Ethylhexyl acrylate and isobutyl acrylate were used as non-polar constituents while acrylic acid and acrylamide provided the more polar constituents to
regulate the cohesive force of the adhesive. The amounts of initiator, water and
emulsifier (nonylphenol) were varied to obtain the best adhesive properties at the
given copolymer composition. The resulting adhesive showed the desired balance
of low tack and good adhesive strength in combination with a wide variety of
substrates, which made it useful as a removable adhesive for many applications.
The product was characterised by viscometry, measurements of tack and peel
strength, FTIR, DSC, and microscopy. COL0002401
