Article: Reactive acrylic liquid rubber with terminal and pendant carboxyl groups as a modifier for epoxy resin.

INTRODUCTION

Epoxy resins are a class of versatile thermosetting polymers, which are widely used in structural adhesives, surface coatings, and composites [1]. This is because of their high strength, low creep, very low cure shrinkage, excellent resistance to corrosion, and good adhesion to many substrates [1, 2]. A major drawback, which inhibits further proliferation of epoxy resins into various industrial applications, is that in the cured state they are brittle materials having fracture energy of about two orders of magnitude lower than engineering thermoplastics and three orders lower than metals [3]. Hence, the modification of epoxy resins to impart fracture ...
