Investigation of the Influence of UV-Irradiation on Thermal Stability of Binary Systems on the Basis of Polyethylene Glycol Fumarate with Some Vinyl Monomers

Original language description

This work is devoted to the investigation of continuous exposure to UV-irradiation on thermal stability of polymeric base of sealants. The copolymers of polyethylene glycol fumarate with acrylic and methacrylic ac-ids, and acrylamide of the composition of “unsaturated polyester : vinyl monomer” similar to 35:65 mass.% (corre-spondingly) were chosen as the polymer base. The samples were analyzed on microscope to the presence of microcracks as a result of exposure to UV-irradiation on them. The studied samples were evaluated visually on color change and the appearance of turbidity. Thermal stability of the studied polymeric base was deter-mined by establishing the temperature of the start of thermal deformation by thermogravimetry before and af-ter the process of UV-irradiation within 21 days. It was established that for the polymeric base with acryla-mide in its content the temperature of the start of thermal deformation had reduced after exposure to UV-irradiation. In contrary, for the polymeric bases with acrylic and methacrylic acids in their composition the abovesaid thermal index almost had not changed after affecting with UV-irradiation on the samples.
