Abstract

Abstract: For the gel network formed in the polycondensation of A_a-B_bC_c type, two different methods are proposed to calculate the number of dangling chains. The corresponding numerical results are also presented by taking the A_4-B_2C_2 reaction system as an example. It is shown that at a low conversion, the dandling chains display mainly the treelike structure with many branched chains, but these branched chains decrease at a high conversion. The present result can provide a possible clue for understanding the viscoelastic properties of polymer gel material.

Key words: polycondensation reaction, gel network, dangling chains
