“…Attempts have been made to relate the NMR line widths to the PVC-plasticizer interaction parameter. 4 Novikov et al used the second moment of the NMR absorption line ∆H 2 2 to obtain some idea of the interaction between PVC and plasticizer. 5 The mobility of the plasticizer molecule in PVC was determined by measuring the spin-spin relaxation time, T 2 , of plasticized PVC samples by the spin-echo method.…”

Solid state 13 C CP/MAS studies of poly(vinyl chloride) (PVC)-bis(2-ethylhexyl) phthalate (DOP) have been carried out to elucidate the dynamics of polymer-plasticizer interaction at the molecular level. 13 C NMR spectra, spin-lattice relaxation time T1(C) and spin-spin relaxation time T2(C) were obtained for various PVC-DOP samples. Line widths of 〉CHsCl show a sharp increase due to the strong hydrogen-bonding interaction between the 〉CdO (ester) group of DOP and 〉CHCl of PVC with various concentrations of DOP. The spin-lattice relaxation time T1(C) also confirms the presence of a strong interaction due to hydrogen bonding. The less mobile intermediate phase is mostly affected by the presence of plasticizer. The spin-spin relaxation time T2(C) shows that DOP is a mixed type plasticizer showing the features of both molecular and structural type plasticization.

“…These authors developed a method for estimating thermodynamic parameters of mixing of filled composites that is based on the use of the ther modynamic cycle including dissolution of a composite and wetting of the filler surface. This approach was successfully applied in [8,9] to describe the thermody namics of mixing of glassy composites based on PVC; PMMA; and their VC-MMA copolymers filled with chalk, pearlite, aerosol, and a number of other dis persed inorganic and organic materials. Investigations were mostly performed for composites containing small amounts of fillers.…”

Influence of interfacial adhesion and the nonequilibrium glassy structure of a polymer on the enthalpy of mixing of polystyrene-based filled composites

et al. 2012

View full text Add to dashboard Cite

For composites based on polystyrene, the styrene-butadiene copolymer, and polybutadiene filled with various kinds of zinc oxide powder, the enthalpy of mixing is calculated in the entire range of filler con tents on the basis of calorimetric measurements with the use of the thermochemical cycle. It is shown that, when the polymer is in excess in the composites based on polystyrene and its copolymer, the enthalpy of mix ing is negative, whereas at a high content of the filler, this value is positive. The alternating sign pattern of the concentration dependence of the enthalpy of mixing is interpreted in terms of the superposition of the nega tive contribution of the enthalpy of the interfacial adhesion interaction of a polymer matrix with the filler and the positive contribution due to a gain in the level of nonequilibrium of the glassy matrix near the surface. A thermodynamic model that makes it possible to separate these contributions and to describe the experi mental curves of the enthalpy of mixing for the composites is advanced.
