Impregnation of Ultra High Density Polyethylene with Unsymmetrical Disulfides in Subcritical Freon Media

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.

Key words: subcritical freons, impregnation, ultra high density polyethylene, implants
