“…The main reason for this behavior could probably be explained by its highest hydrophilicity and molar ratio of PLA, providing a larger amount of ester bonds than others. These bonds were subjected to scission by lipase and more hydrophilic nature that increase the interactions of water with the graft copolymers

PLA % = 100 - ([], \frac{((), \frac{1 + 2 + 3 + 5 + 6 + 7 + 8 + 9 + 10}{18})}{(\frac{f}{3}) + (\frac{1 + 2 + 3 + 5 + 6 + 7 + 8 + 9 + 10}{18})}) \times 100

The syntheses of polypropylene‐graft‐poly(l‐lactide) copolymers (PP‐g‐PLAs) via copper (I)‐catalyzed azide‐alkyne cycloaddition “click” reaction (CuAAC) using azide side‐chain functionalized polypropylene (PP‐N3) and alkyne end‐functionalized poly(l‐lactide) (PLA‐Alkyne) were reported. The CuAAC was then applied to azide and different feeding ratios of alkyne functional polymers to give PP‐g‐PLAs that were characterized by FTIR, 1H‐NMR, GPC, DSC, and WCA measurements. The CuAAC click reaction was achieved by two different feeding ratio (PP‐N3:PLA‐Alkyne = 1:5 and 1:10) and thermal, biodegradable, and surface properties of obtained graft copolymers were investigated. The molar ratio of PLA were calculated as 72.7 (PP‐g‐PLA‐1) and 78.4% (PP‐g‐PLA‐2) by 1H‐NMR spectroscopy. The water contact angle (WCA) values of PP‐g‐PLA‐1 (81o ± 1.3) and PP‐g‐PLA‐2 (75o ± 1.6) copolymers were compared with commercial chlorinated polypropylene (PP‐Cl) (90o ± 1.0), suggesting a more hydrophilic nature of desired graft copolymers produced. Conversely, the enzymatic biodegradation studies revealed that the weight losses of graft copolymers were determined as 13.6 and 22.1%, which is about 4% for commercial PP‐Cl sample. Thus, it was clear that this simple and facile method was effective in promoting biodegradation of commercial polypropylene and attractive particularly for worldwide environmental remediation goals. © 2018 Wiley Periodicals, Inc.

“…After the hydrogel sample was removed from the degradation solution, it was cleaned with deionized water and dried at 50°C under vacuum for 24 hours. The weight loss of PAMU‐ and CS‐based hydrogel sample was calculated using Equation :

Weight loss (() %) = ((), \frac{W_{before} - W_{after}}{W_{before}}) \times 100,

where W after and W before are the weights of the hydrogels after and before in vitro biodegradation.…”

In this study, biodegradable and antibacterial poly(azomethine‐urethane) (PAMU)‐ and chitosan (CS)‐based hydrogels have been prepared for controlled drug delivery applications. Structural and morphological characterizations of the hydrogels were performed via Fourier transform‐infrared and scanning electron microscopy analyses. Thermal stability, hydrophilicity, swelling, mechanical, biodegradation, protein absorption properties, and drug delivery application of PAMU‐ and CS‐based hydrogels were also investigated. The swelling performance of the hydrogels was studied in acidic, neutral, and alkaline media. Swelling results showed that the hydrogels have higher swelling capacity in acidic and alkaline media than neutral medium. Biodegradation experiments of the hydrogels were also studied via hydrolytic and enzymatic experiments. The drug release property of the hydrogel was carried out using 5‐fluoro uracil (5‐FU), and 5‐FU release capacity of the hydrogels was found in the range from 40.10% to 58.40% after 3 days.
