Study of the Effect of Filling Thermoplastic Medical Polyurethane with PVA, PLA or Diatomite on the Relaxation Times Distributions of 1H NMR
Abstract
In this work, to characterize the mobility of diferent sections of the macromole‑ cules of polyurethane (PUR), polyvinyl alcohol (PVA), and polylactic acid (PLA), as well as the density of crosslinks of the polymer chains when using fllers, we used the distributions of spin–lattice and spin–spin relaxation times for the protons. It is shown that the rigidity of the thermoplastic polymers depends on the sizes of the granules of the diatomite fller, which can embed in the polymer matrix. Conse‑ quently, relaxation times are reduced. If PLA is the fller of PUR, the dynamics of the molecules in the chains and the spin–spin interaction of the protons are afected by the crosslinking of PUR by PLA. An increase in crosslinks density reduces the rate of polymer degradation.
