We report results of the computer simulation of the kinetic gelation process of the formation of a two-dimensional network. The simulation is performed on a basis of a two-dimensional triangular lattice. Our aim is to analyze the distribution Ng(s) of the pore size s in the network, as dependent on the concentration of the linear polymer molecules in the system. Here we demonstrate, that for some critical concentration of the molecules the obtained distribution is close to Ng(s)\propto s-\tau and it does not depend on the probability of merging. The obtained value of the exponent \tau agrees with the result for clusters in the theory of percolation on the two-dimensional lattice.
