The influence of formation conditions on structure and properties of reaction products from two different macromolecules (paired polymers) such as polystyrene and poly(1,l ,2-trichlorobutadiene) or polystyrene and poly(viny1 chloride) is investigated. Mechanical properties, molecular mobility, heat resistance, thermostability, and fire resistance are shown to be regulated over a wide range by changing the molecular weight of the initial polymers, their ratio in the reaction mixture, etc. The interaction of different macromolecules in solution to form paired polymers is analyzed theoretically and experimentally. An analysis of structure and properties of the resulting products by refractometry, viscometry, sedimentation velocity, statistical analysis, and others shows that paired polymers are systems of the "coil-in-coil" type held together by chemical bonds in the zones of mutual penetration.
It was established by Fourier-transform IR and IH NMR spectroscopy that a portion of the units of poly(l,t,2-and 1,2,3-trichlorobuta-l,3-diene) chains rearrange with migration of the allylic chlorine (l--4%) and allytic hydrogen (3--10%) under the influence of chloroform. Rearrangement with the migration of hydrogen under the influence of CDCI3, CCI 4, and THF was also observed.
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.
