Abstract

Fremgangsmåte for fremstilling av polyoksymetylenhomopolymerer eller kopolymerer ved homopolymerisering eller kopolymerisering av trioksan eller ytterligere av egnede komonomerer, hvori trioksan som fremdeles innbefatter restmonomerer først fremstilles i et monomeranlegg og blir avgasset i et eller flere trinn for å gi en eller flere dampstrømmer (13, 14) som blir, hvis passende, matet til en kjøler (K) hvori de kondenserbare fraksjonene til disse dampstrømmene kondenseres for å gi et kondensat (15) som resirkuleres til polymerisasjonsreaktoren (P) og en eller flere gassformige formaldehydinnbefattende strømmer (16) og også en delvis avgasset polyoksymetylenhomopolymer eller kopolymer (17) som. mates til en ekstruder (E) eller knær og blandes med vanlige additiver og prosesseringshjelpemidler i denne. for å gi en polymersmelte (19) og. ekstraksjon av den formaldehydinnbefattende ekstruder eller knaer avgassen (18) fra ekstruderen (E) eller knaeren,. hvori de formaldehydinnbefattende sekundære strømmene (14, 16, 18) for polymeranlegget resirkuleres direkte uten tilsetting av hjelpestoffer til monomeranlegget, er beskrevet.
