description Method for coagulating polymer dispersions with heat sensitizing agents of the general formula (I) R1¢- NHCO - (O - CHR2 - CHR3)x - (O - CHR4 - CHR5)y - R6!n where R1 represents an optionally substituted alkyl, cycloalkyl or aryl radical, as remains after the removal of n isocyanate groups from a corresponding n-valent isocyanate; n is a number from 1 to 20; R2 to R5 represent independently or one another hydrogen, C1 C4-alkyl, phenyl or chloromethyl; x stands for the numbers 1 to 100; y stands for the numbers 0 to 50; and R6 represents O-aryl, O-aralkyl, O-alkaryl, O-CO-alkyl, O-CO-aryl, NH-CO-alkyl, NH-SO2-alkyl or O-alkyl. These new heat sensitizing agents provide at room temperature stable latices which coagulate completely when heated.
