Double complex salts network

Several isopolymolybdates which have been isolated from solution are polymeric or appear to have structures that do not persist in solution. These include the trimolybdates M2M03O10 XH2O, obtained as fibrous crystals from appropriately acidified solutions. The structures of Rb2Mo3Oi0H2O and RbNaMo3Oio contain infinite double chains of edge-shared MoOs octahedra.42 From more acidic solution polymeric pentamolybdates [MMosOi6H(H20)] slowly crystallize. The structure of the potassium salt reveals a complex three-dimensional network of MoOe octahedra.43... 

Abstract The nonlinear viscoelastic behavior of cured rubber is quite different from that of uncured compound, since the presence of crosslink networks. The factors for the influence of the crosslink networks on the nonlinear viscoelastic behaviors of cured rubbers are very complex and obscure. One of the reasons is that the crosslink networks may be consisted of several different types of networks. However, there are few literatures reporting the nonlinear viscoelastic behaviors of cured mbbers with mutle-networks. We reviewed the literatures dedicated to the topic of the non-linear viscoelasticity of simplest mutle-networks—double-network and summarized the useful information as much as possible in the present paper. Song s transient double-network model, double-network formed by twice curing and the specific crosslink network formed in metal salts of unsaturated carboxylic acids reinforced rubbers are introduced in detail.
