    Abstract: A method for producing a porous cross-linked polymer sheet capable of slicing quickly is provided. This method comprises a step for obtaining a porous cross-linked polymer by forming and polymerizing an HIPE, a step for dehydrating the porous cross-linked polymer, and a step for subsequently slicing the dehydrated porous cross-linked polymer. According to this invention, by performing the step of dehydration prior to the conventional step of slicing, it is made possible to prevent the porous cross-linked polymer from adhering to the blade and the guides provided for a slicer, and allow the slicing to be attained quickly. By removing the salt from the polymer, it is further made possible to prevent a production device from gathering rust and the porous cross-linked polymer from permitting adhesion of rust thereto.

    Abstract: A lightweight absorbent foam is produced using a high internal phase emulsion (HIPE), the production of which incorporates the use of capillary viscosity measurements as an in-line diagnostic for HIPE quality. The in-line diagnostics yield measurements of viscosity slope and amplitude. These measurements offer several advantages for monitoring emulsion quality, including stable high resolution measurement of hardware-independent parameters of the whole flow, without the need for sampling.

    Abstract: The difficulty in readily removing water from cured water-inthermosettable resin emulsions has been overcome by adding to the emulsion from about 0.005 to 10 parts per 100 parts of emulsion of a polyalkylene oxide block copolymer, nonionic surfactant wherein the hydrophobe portion of the nonionic surfactant has a molecular weight of at least about 1,000. Dewatering of the cured emulsion may be readily effected even at ambient temperatures and at elevated temperatures without cracking or damage to the porous thermoset resin.
