Relationship between superficial response to environmental changes and adhesive property of polyurethane cross‐linked polyacrylate network

摘要

AbstractA polyacrylic network containing carboxyl groups was cross‐linked with polyurethane. The dynamic contact angles (DCA) on specimens were estimated in water. The effect of ingredient ratio and average molecularM̄nof poly(oxypropylene glycol) (PPG) on DCA were investigated. Data obtained are correlated with 180° peel strength by using the polymer network as an adhesive to adhere both poly(vinyl chloride) (PVC) and polyethylene (PE) film. Results reveal that there is correlation of the surface response to bilateral adhesion of polar and nonpolar substrates. © 1994 John WileySons,
