Abstract: The invention relates to a process for the preparation of a gel material which is not free-flowing, is reversibly transparent as a function of temperature and comprises nonionic and/or nonionically acting surfactants as clouding components. The preparation of the gel material can be integrated into the customary production process for laminated glazing in a simple manner and produces frost-stable glazing which can be employed universally indoors and outdoors. When applied, the strength of the system is so high that it is no longer free-flowing at all and bulging of the laminated pane and running-out are therefore no longer possible.

Abstract: The invention provides a process for the preparation of large-particle, aqueous plastic dispersions, which permits targeted adjustment of particle size. The process comprises a system which controls the particle size and comprises the step of polymerizing a monomer in the presence of an anionic emulsifier; a substantially non-branched, nonionic, water-soluble polymer auxiliary; and alkali metal and/or ammonium ions not bonded to emulsifier. The polymer auxiliary can be prepared reproducibly with regard to its agglomerating effect.
