摘要：

This study describes the chain extension, with polycaprolactone diols, of polyurethane-graft-poly(butyl acrylate)s which were first prepared by the step growth polymerization of a mixture of diphenylmethane-4,4'diisocyanate (MDI) and alpha,alpha'-dihydroxyl-poly (butyl acrylate)s. The success of the chain extension reaction was studied and confirmed by H-1 NMR, SEC and DSC analysis. The incorporation of polycaprolactone sequences in the polyurethane chains modified their specific adhesive properties, bringing cohesion to the material, as demonstrated by tack measurements.
