The structure of synthesized oligomeric initiators and block-copolymers has been investigated by IR-spectroscopy and transmissional optical spectroscopy. The polymeric materials has been worked based on an oligourethane epoxide modifier and epoxy resins that enabled improving tensile strengths and elongation of epoxy materials. The modification of cellulose and wood flour by the way of grafting methyl methacrylate, treating with urea, and carboxilic oligodiene lead to improving the properties of composites using these materials as fillers. The polymeric composition containing hydroxypropyl methyl cellulose has been created, which provides forming adhesive bond with high tensile strength, shock strength, strength at rupture, and low water-absorption.
