Figure 7. Efficiency of EPDM (POLY) grafted with TPA on the photoageing of EPDM (POLY).

The pronounced efficiency of EPDM (POLY) grafted with TPA on the photoageing of the parent polymer is reported on Figure 7. Similar experiment after vulcanisation (not shown) reduced the photo-oxidation rate by a factor 1.5 both for virgin and stabilized films. 

Thermalageing at 80°C. The remarkable efficiency of EPDM (POLY) grafted with TP A can be seen on figure 8. Fig. 8a shows that the stabilization with 10 % w/w of EPDM-TPA in the crude elastomer. The effect of vulcanization is reported in fig. 8b, in this time scale the increase of stability is only seen on the virgin polymer. 

Ohya et al. reported poly(ethyleneglycol)-grafted chitosan nanoparticles as peptide drug carriers. The incorporation and release of insulin was dependent on the extent of the reaction of poly(ethyleneglycol) with chitosan [190].

After grafting with AM the Nls peak appears, the Cls peak has only one side peak (C=0) at about 286 eV and the Ols peak is dominated by 0(C=0) which indicates an almost complete cover of grafted poly(acrylamide) chains 4 CH2-CH(CO-NH2) n The grafting kinetics (Figure 11) is similar to that ot PE and PP substrates (comp.

The enzymatic polymerization of lactones could be initiated at the hydroxy group of the polymer, which expanded to enzymatic synthesis of graft copolymers. The polymerization of c-CL using thermophilic lipase as catalyst in the presence of hydroxyethyl cellulose (HEC) film produced HEC-gra/f-poly( -CL) with degree of substitution from 0.10 to 0.32 [102].
