【Abstract】 In the present study, acrylic hot melt pressure sensitive adhesive composed of acrylic copolymer and ionic corsslinking agent was synthesized by means of bulk polymerization. The synthesized copolymer was made of three components: soft monomer; butyl acrylate and 2 ethyl hexylacrylate; hard monomer; methyl methacrylate, methyl acrylate, vinly acetate or styrene; functional monomer; acrylic acid, maleic anhydride and acrylamide. The synthesis discipline of the acrylic copolymer and the influences of copolymer component on the melting viscosity, 180° peel strength, tack and holding power of the pressure sensitive adhesive were discussed in the paper. Finally, the pressure sensitive adhesive with excellent properties was obtained, which could be used in the preparation of tape easily.更多还原
