Аннотация:Comb-shaped polymers containing side polyoxyethylene blocks were synthesised in high yield. For the case of model compounds, the possibility of using the polymers obtained as matrices for chemical optical sensors was assessed. The influence of the length and number of block substituents on the swelling of the polymers in water was investigated. Almost 100% binding of the model compounds by the polymer matrix was observed, together with the almost complete absence of hydrolysis of the model compounds for 1 h. The results obtained demonstrated the potential for using these polymers as matrices for chemical optical sensors.
