Method for polarizing at high field strengths, shaped articles made from polymers provided at both sides with electrically conducting contacts, characterized by the polarization voltage U.sub.p (t) corresponding at least to an initial field strength of 4000 kVcm.sup.-1 which is applied to the shaped articles made from polymers having with their contacts a capacity C.sub.1 at temperatures preferably above 2/3 the melting temperature of the shaped articles, by means of variable, high-voltage resistance, charge-limiting polarization capacitors of a capacity C.sub.2, wherein C.sub.2 >>C.sub.1 is valid as initial state, and wherein C.sub.2 is selected in such a way that the initial maximum polarization voltage U.sub.p (t.sub.o) is applied only momentarily to the shaped article and will drop after completed polarization to a value U.sub.p (t) which will amount to approximately one half of U.sub.p (t.sub.o).
