Using of a Molecular equation of a first dendrimer surface and its relation to dendrimer molecular radios, it is possible to suggest the number of generation. Whereas a relative molecular weight is affiliated to the number of molecule formed in structural cells and on the other hand, structural cells have definite and determined dimensions, so by a simple replacement, the dendrimer molecular weight was directly related to its generation number. Data analysis derived from specific equation was shown that the prediction of a dendrimer molecular weight may be applicable by a specific generation. Molecular weight of polyamido carboxylic acid dendrimer with specific number of generation could be theoretically estimated using the following eqs. (4) and (5). y = log Mw =2.0703 + 0.0844Ri (4) =2.6339 + 0.4750Gn (5) Ri and Gn are molecular radius and number of generation respectively. Such equations would result the molecular radius of the dendrimer. In this invented model there is no need to experiments and it can be key value to evaluate the experimental data. |
