    Abstract: Process for producing insulating panes, comprising at least two panes which are arranged in parallel at a distance of from 5 to 50 mm, are approximately of the same size and are connected at the edges such that they are airtight or gastight in a manner known per se. Loose air-impermeable or gas-impermeable sheets connected to the seals at the pane edges in an airtight or gastight manner rest on the inner sides of the panes, the space between the sheets is sealed with small aerogel balls, said space is then closed off in a fully airtight or gastight manner and is subsequently evacuated to the desired extent by means of a suitable device (tube), and air or an inert gas at normal pressure is fed in at the same time between the sheets and the panes through one or more openings or tubes. The opening at the evacuating point is then closed off in a vacuum-tight manner, while the openings between the panes and sheets are either closed off or, if appropriate, remain connected to the outer air via a drying agent.

    Abstract: Gels for thermotropic sheets are claimed which are obtd. by light-radiation of a mixt. comprising (A) a non-crosslinked polymer (pref. 5-40 wt.%); (B) a radically-polymerisable monomer (pref. 1-30 wt.%); and (C) water and/or an org. solvent (pref. 30-94 wt.%). Pref. a photoinitiator is opt. also present. Polymer (A) has transparency changes in a 10 wt.% aq. and/or org. solvent soln. and is poly-N-vinylcaprolactam, a copolymer contg. at least 20 wt.% N-vinylcaprolactam, or a polyvinylether. Monomer (B) forms a 3-D network on light-irradiation and ether does not have thermotropic properties of the type specified above or has such properties at at least 20 degrees C above the switching region for polymer (A). (C) is water.
