Abstract

In this work, acrylic resins consisting of difunctional poly (butyl acrylate) (PBA) were prepared via atom transfer radical polymerization. PBA acrylic resins with two different molecular weights were synthesized and the terminal groups of the bifunctional PBA were substituted with an acrylate group (A type), a silane group (S type), and a vinyl group (V type). The resulting PBA acrylic resins were characterized by gel permeation chromatography and nuclear magnetic resonance spectroscopy. These resins having different terminal groups were cured using thermal curing, UV curing, and moisture curing. The mechanical properties were examined using tensile and peel tests according to the molecular weight and the type of end groups.
