A process for preparing low-density flexible polyurethane foams obtained, in the absence of expanding agents of chlorofluoroalkane type, by the polycondensation of an organic polyisocyanate with at least one polyol of equivalent weight exceeding 50 and functionality equal to or greater than 2, in the presence of an expanding system comprising water and dimethyl carbonate (DMC).

Disclosed are poly(ethylene-co-diethylene terephthalate) polyesters useful for making thin films. The polyesters have a diethylene glycol repeat unit component of about 10-30 mol %. These polymers can be converted into thin films and are useful as protective barrier films, especially in packaging applications. These copolyesters can be used to make biaxially oriented films for metal lamination.

Production of ice beer involves fermenting wort, yeast being added to the new or green beer, and terminating the fermentation is arrested on reaching the desired degree. The yeast is removed and the beer is cooled to a temperature in the boundary region between solid and liquid phases. Ice crystals resulting from cooling are removed and the ice-free beer is stored at the same temperature, checking...
