The interpretation of the results of thermal measurements followed over decades the Arrhenius law. In recent years an apparently different interpretation (Eyring's equation) has been emerging in the literature on polymers. As the main reason for this

Numerous interpretations have already appeared concerning the compensation effect (CE). A recent proposal, associated with the study of polymers, suggests a linear relationship between Eyring's activation enthalpy and activation entropy as an explana

A new graphically evaluable linear method is suggested for the determination of the reactivity ratios of copolymerization. The main advantage of the proposed equation (5) is that it is very well adaptable for visual determination of the applicability

Cyclodextrin-cellulose copolymers were produced by immobilization of cyclodextrins on cellulose. These products combined the favourable properties of cellulose /adsorption, wettability/ with the complex forming capacity of cyclodextrins. In these pol
