Abstract

Fremgangsmåte for fremstilling av en ABA-blokk-kopolymer med et midtsegment mellom to endesegmenter, hvor hvert endesegment er en oxiranholdig acryl- eller methacryldel, og hvor midtsegmentet er en acryl- eller methacryldel som ikke inneholder oxi-rangrupper.BA-blokk-kopolymeren fremstilles ved omsetning av be-standdelene ved hjelp av gruppeover-føringspolymerisasjonsteknikker, idet en monofunksjonell initiator anvendes med egnede monomerer for å polymeri-sere sammen og i rekkefølge et første endesegment og deretter et midtseg-. ment, hvoretter det tilsettes koblingsmiddel for å bringe to midtsegmenter til å reagere med hverandre for dannelse av ABA-blokk-kopolyme-ren, eller en oxiranholdig initiator omsettes med egnede monomerer for polymerisering med midtsegmentet, hvoretter koblingsmiddel tilsettes for å bringe to midtsegmenter til å reagere med hverandre for dannelse av AB-blokk-kopolymeren.A process for producing an ABA block copolymer having a middle segment between two end segments, each end segment being an oxirane-containing acrylic or methacrylic moiety, and wherein the middle segment is an acrylic or methacrylic moiety that does not contain oxygen groups. The BA block copolymer is prepared by reacting the constituents by means of batch transfer polymerization techniques, a monofunctional initiator being used with suitable monomers to polymerize together and in sequence a first end segment and then a middle segment. after which coupling agent is added to cause two middle segments to react with each other to form the ABA block copolymer, or an oxirane-containing initiator is reacted with suitable monomers for polymerization with the middle segment, after which coupling agent is added to bring two middle segments to react. react with each other to form the AB block copolymer.
