The reaction of Pyrogallol with Formaldehyde is extremely quick. Any suggestions for controlling the condensation reaction in preparation of pyrogallol-formaldehyde (resol) to obtain blister-free nanocomposite samples.
How about doing that as a thin layer on a thick copper or aluminum plate, pre-chilled by, say, mixture of dry ice (solid carbon dioxide) plus acetone. E.g. thin layer of one component chilled, then sprayed with the other component.
Hello Vijay,
Additional thoughts: You will probably want to avoid condensation of water vapor from the air on the chilled surfaces - it might affect the reaction and the product. Therefore using a glove box with a lot of a dessicant inside may be a good idea.

The reaction of Pyrogallol with Formaldehyde being fast you have to carry the reaction at a low temperature. if necessary change the solvent.
