The effects of the content of chain transfer agent(CTA) N-dodecyl mercaptan(NDM) and inner cross-linking agent N-methylol acrylamide(N-MAM) on the properties of acrylic pressure-sensitive adhesives were discussed. In the polymerization process, acrylic acid(AA) and N-MAM have the similar impact on the properties of the emulsion. At a constant CTA content, the shear force of the emulsion increases with the increasing of N-MAM content, 180° peel strength and tack force increase first, then decrease. At a constant cross linker content, shear force decreases, 180°peel strengths and tack force increases with the increasing of CTA content. When the mass fraction of CTA and N MAM are 0.06% and 2% respectively, PSAs have good integrative performances.
