Poly(2-((3-(1-(2-(dimethylamino)ethyl)-1H-1,2,3-triazol-4-yl)propanoyl)oxy)ethyl methacrylate), P1, which has great attention due to a lot of applications, was prepared and characterized depending on temperature and time. P1 solution properties were probed with small angle neutron scattering (SANS) and dynamic light scattering (DLS). P1 formed clusters by hydrophobic effect and weakened hydrophobic effect by polymer dissolution with incubation time consequently attributed to decrease in size or disappearance of clusters. The temperature dependent cluster formation can be explained by hydrophobic effect with both the increase in scattering intensity by clusters at low q region and the decrease in correlation length of polymer at high q region based on ‘two Lorentz model’ analysis. Decreasing intensity of clusters with incubation time shows weak cluster formation. Porod exponent reflects the dissolution change of P1 from mass fractal to loosen structure as incubation time increases. |
