Investigation  of  Swelling  Behaviour  of   Synthesized  Novel  Hydrogels  based on different  vinyltrialkoxysilanes

Synthesis  of   hydrogels  became  one  of  the  most  popular  research  topic  in recent  years. Hydrogel  is  a network  of  polymer  chains  that  are hydrophilic, sometimes  found  as  a  collodial  gel  in  which  water  is  the  dispersion medium. Hydrogels  are  highly  absorbent  natural  or  synthtetic polymers. In  our  studies we  have  focused  on  interaction  between  acrylamide(AMc)  and   2-acrylamido-2-propane methylsulfonic acid(AMPS)  and use  of  different  vinyltrialkoxiysilanes as crosslinkers,  as novel hyrogel.  In order to investigate the hydrolysis  and condensation  behaviour  of   different  alkoxy chain length of  different  vinyltrialkoxysilanes , Poly(acrylamide-co-2-acrylamido-2-methylpropane sulfonic acid-co-vinyltrialkoxysilane) was  sytnthtesized  and  clear  brittle  films  were cast  by  dissolving  in  water. The swelling ratio and swelling capacities of the finely prepared films which  were synthesized in distilled water medium  were investigated by using gravimetric  Equilibrium Swelling Ratio (ESR) medhod. Synthesized superabsorbent hydrogels were  charazterized by  liquid state  29Si-NMR, 1H-NMR, FT-IR, DSC and STA. Molecular weight of  synthesized polymers were determined by Dillute solution Viscometry and viscosity of different polymer concentration solution were  obtained  from Brookfield DV-II  viscometry. A well defined  correlation was investigated between resisstant strenght of  different alkoxy chain lenght of vinyltrialkoxysilanes and maximum equilibrium swelling ratio, this correlation was also supported  by  molecular weight results  and viscosity values
