Abstract

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 acids, and acrylamide of the composition of “unsaturated polyester: vinyl monomer” ~35:65 mass.% (correspondingly) 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 determined by establishing the temperature of the start of thermal deformation by thermogravimetry before and after the process of UV-irradiation within 21 days. It was established that for the polymeric base with acrylamide 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 above said thermal index almost had not changed after affecting with UV-irradiation on the samples.
