Description
Summary:An interfacial polymerization reaction was used to prepare a pressure-sensitive adhesive paper that did not require release paper (PSAPwithout). Filter paper impregnated with an oil–water emulsion comprising ethylenediamine (EDA) and pressure-sensitive adhesive (PSA) was immersed in a solution of terephthaloyl chloride in cyclohexane, and the polyamide film containing the PSA attached itself to the treated paper surface. The pressure-sensitive-adhesive paper (PSAP) prepared by employing this interfacial polymerization did not require the use of release paper. In the case of the PSAPwithout samples prepared using 2.5%, 5%, and 10% EDA and 60 mL of a 35% PSA–cyclohexane solution, the peel strengths were 460, 493, and 438 mN, respectively. The PSAPwithout prepared under these conditions adhered sufficiently to the aluminum foil after a hot-press treatment. An EDA concentration of 5% and a 60 mL volume of the 35% PSA–cyclohexane solution maximized the adhesiveness of the PSAPwithout.
