The acrylic copolymers, which were used as base polymers for the pressure sensitive adhesives, were synthesized by solution polymerization of 2-ethylhexyl acrylate, ethyl acrylate, laurylacrylate and acrylic acid with 2,2’-azobisisobutyronitrile as an initiator. Various kinds of acrylic copolymers were prepared by using various different contents of epoxy-type crosslinking agent (0, 0.5, 1.0, and 2.0 phr) and lauryl acrylate (5.0, 7.5, and 10.0 wt%). The acrylic copolymers played an crucial role in controlling the anti-shock properties of adhesives on thin silicon wafer. The effect of acrylic copolymer chain length on the anti-shock and the adhesion properties of acrylic copolymer adhesives were also studied. |
