Abstract: | Graft copolymerization of bis (2-methacryloyl oxy ethyl) acid phosphate (BAP) on to chitosan initiated by potassium per sulphate (KPS) under N2 atmosphere has been studied. The effect of polymer concentration, monomer concentration, polymerization temperature, initiator concentration and polymerization time on the grafting yield have been investigated.
The copolymers were characterized by FTIR, SEM, DSC, and contact angle measurement. Swelling and dissolution behaviour of grafted polymer was followed in different buffer solutions (pH = 3, 7, and 11).

Azot atmosferi altında potasyum persülfat (KPS) redoks başlatıcısı kullanılarak farklı konsantrasyonlardaki kitosan sulu çözeltilerinin bis(2-metakriloil oksi) asit fosfat (BAP) ile kopolimerizasyonu incelenmiştir. Polimer konsantrasyonunun, monomer konsantrasyonu, polimerizasyon sıcaklığı, başlatıcı konsantrasyon ve polimerizasyon süresinin % aşılama etkisi çalışılmıştır.
Aşılı kopolimerler FTIR, SEM, DSC ile karakterize edilmiş ve temas açısı ile hidrofilik özelliği incelenmiştir. Sentezlenen yeni fosforile kitosan filmlerin morfolojileri ile termal davranışları SEM ve DSC analizleri ile test edilmiştir. Aşılı polimerin şişme davranışı farklı pH' lardaki tampon çözeltilerde (pH = 3, 7 ve 11) test incelenmiştir.
