    摘要： A homopolymer or copolymer which contains, as a monomer unit, at least one styrene of the formula ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 independently of one another denote hydrogen, fluorine or partly or completely fluorinated alkyl or alkoxy andR.sup.4 and R.sup.5 independently of one another represent hydrogen or fluoride, the total number of fluorine atoms in the radicals R.sup.1 to R.sup.5 being at least 3 and the total number of carbon atoms in the radicals R.sup.1 to R.sup.3 being at most 8. The homo- or copolymers can be prepared by vinyl polymerization. They are useful as lenses or other components in an optical system where they have a refractive index n.sub.D of 1.42 to 1.55 with an Abbe number v.sub.D of 30 to 50.

    摘要： It is possible to remove quantities of heat from exothermically running polymerization reactions of vinyl monomers in heterogeneous phase, in a sophisticated manner by adding liquids to the reaction medium for the removal of heat and to regulate the reaction temperature, which liquids do not dissolve the polymer under the reaction conditions and the boiling temperatures of which are lower than or are identical to the technically predetermined reaction temperatures under the polymerization conditions which are applied, and the heat which is released in the reaction system is removed by evaporating these liquids.
