Kinetics of Gelation Monitored Through Dynamicsd modulus near the gel point have been reported for a number of systems.. However problems exist comparing theory and experiment because of the inability to perform a true zero shear rate experiment particularly given the divergence of the longest relaxation time in the gelling solution.

Novel Network Structures: Fractal-Rigid-Flexible Networksments and their effects on elasticity from different points of view. The long dispute in the literature has now probably been solved by computer simulation where networks with and without entanglements can be generated very simply.These results seem to favor a strong contribution of entanglements to the modulus.

Investigation of Gelation Processes and Gel Structures by Means of Mechanical Property Measurements(TiO.), zirconia (ZrO.), etc.] or organic (phenol-formaldehyde resins, epoxies, etc.). Both the inorganic and iorganic covalent types have been used to prepare aerogels, and the inorganic ones are now much used to prepare high-tech ceramics by the new sol-gel route.

Fractal Properties of Branched Polymers branched structures. in the vicinity of the sol-gel transition. The latter was studied some years ago, and it was realized very early that the distribution of masses is very broad, and becomes infinitely polydisperse near the gelation threshold. More recently, excluded volume effects were taken int

The Fractal Nature of One-Step Rigid Networks and Their GelsBy the correct choice of monomer size and functionality, f, we were able to prepare networks with stiff segments having . length, .., as short as 6.5Å and as long as 208Å, and rigid branchpoint (crosslink joint) functionality of 3 to 6.. X-ray studies revealed that the dry or swollen networks and th
