Investigation of Physical and Chemical Properties of Thermosetting Copolymers of Polyethylene Glycol Maleate with Acrylic Acid During their "Cold" Curing

Popis výsledku v původním jazyce

The paper presents information on the study of physical and chemical properties of solutions of polyethylene glycol maleate in acrylic acid and products of their &quot;cold&quot; curing. The weight-average molecular weight of the initial polyethylene glycol maleate was established using the GPC method. The value of the degree of unsaturation of both the initial unsaturated polyester and copolymers based on it was determined using the bromide-bromate method. The dynamic viscosity of the polymer-monomer mixture of polyester and acrylic acid was established using viscometry. The density of the stock solutions was analyzed using the pycnometric method and the density of the cured products was determined using the hydrostatic method. The total volume shrinkage of the copolymers was calculated from the obtained density values. The composition of the copolymers was analyzed/studied with the help of HPLC. The degree of swelling of the cured products was also calculated by gravimetric method, and their identification was carried out using IR- and H-1 NMR-spectroscopy. The surface topography of cured copolymers was investigated by SEM. The results obtained indicate to the possibility of controlling the properties of cured unsaturated polyester by varying the initial composition of polymer-monomer mixture depending on its purpose and obtaining on its basis the polymer matrix for the manufacture of bulk products with good physical and chemical properties.
