A discussion of the mechanism of nylon 6

6 dissolving process using CaCl

/MeOH as the sol-vent is presented. The calcium chloride forms a complex compound with nylon 6

6 by breakingthe hydrogen bonds. The melting point of the CaCl

--nylon 6

6 complex was found to be reducedby 91K relative to the pure nylon 6

6 polymer. The role of methanol is somewhat similar to acatalyst. The results demonstrate that the complexation of a Lewis acid （CaCl

） and a Lewis base（nylon 6

6） can be used to probe intermolecular interactions such as hydrogen bonding in polymers

to modify the polymer properties and mediate its solubility and processing.
