Key words: subcritical freons, impregnation, ultra high density polyethylene, implants
For the first time ultra high density polyethylene (UHDPE) samples impregnated
with antibacterial unsymmetrical disulfides (allyl benzothiazol-2-yl disulfide and allyl
8-quinolyl disulfide) were obtained in subcritical freon R22 in the absence of organic
solvents as modifiers. Freon R22 was completely removed from the impregnated samples
that provided a high purity of the final material. Potential implants based on the UHDPE
impregnated with unsymmetrical disulfides were shown to manifest antibacterial and
antifungal activity.
