Shear-Induced Reactive Gelation

In this work, we describe a method for the production of porous polymer materials in the form of particles characterized by narrow pore size distribution using the principle of shear-induced reactive gelation. Poly(styrene-co-diviny...

Highly-branched off-stoichiometric functional polymers as polymer networks precursors

The formation of highly-branched off-stoichiometric polymers from Ax+Bymonomers has been described by the theory of branching processes. The differences in reactivity of functional groups were accounted for. The results of the model give cri...

The Effect of the Gelling Agent on the Gelation Rate and the Formed Sol-Gel Structure

In this paper a combination of colloidal silica and different gelling agents are studied in order to observe the effect of gelation rate on the formed sol-gel structure. Proper ratios of sol matrix materials and gelation agents were...
