| Abstract: | An interpenetrating polymer networks(IPN) of poiy-urethane/polyacrylate (PU/PAA)is prepared to modify heat-resistant, acrylate pressure-sensitive adhesives. The softening point of the modified adhesive can be up to 125℃. The paper analyses and discusses the effects of different preparation technologies on the properties of the adhesive, studiesits heat-resistant mechanism. |
