By free radical addition of ethanedithiol to alkyl- and cycloalkyl-substituted methylene dioxolanes, the bis-adducts tested then as a plasticizer for PVC have been obtained. It has been established as a result of the carried out investigations that the introduction of the synthesized compounds into PVC composition improves the physical-mechanical properties, which has been connected with the availability of sulfur atoms, carbonyl groups and ether bond in the molecules of bis-adducts. The high operational indices from PVCplastics indicate good plasticizing properties of the synthesized bis-adducts, and therefore they can be recommended for practical use.
By copolymerization of cycloalkyl-substituted methylenedioxolanes with maleic anhydride the copolymers, which were subjected to acylation reactions with vinyl carbinol were obtained. It was revealed that as a result of the reaction, the copolymers with various degrees of etherification were obtainedIt found that the obtained etherified copolymers exhibited various UV sensitivity depending on the degree of etherification. It revealed that the availability of highly absorbing fragments such as allyl and carbonyl groups in macromolecules of the etherified copolymers provides these polymers, along with high light-sensitivity, with film-forming properties and good adhesion to quartz substrate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
