摘　　要：对丙烯酸单体的配比及制备工艺进行改进,合成出一种具有超微粘剥离强度的压敏胶。其原理是采用比异辛酯侧链更长的长链烷基酯,通过提高高聚物中羟基的含量,合成出主链较长而侧链较短的高聚物;使用高比例的固化剂,形成网状结构,从而使该丙烯酸压敏胶具有更低的剥离强度,并给出了实际制备案例。An acrylic acid pressure-sensitive adhesive with ultra-low adhesive peel force was synthesized by improving the ratio and the preparation process of acrylic monomer.The principle is to use long-chain alkyl ester with longer side chain than the isooctyl ester and increase the hydroxyl content in the polymer to synthesize a polymer with longer main chain and shorter side chain,and use a curing agent at high ratio to from the network structure to reduce the peel force of the acrylic acid pressure-sensitive adhesive.An actual preparation example is provided.
