Description
Verfahren zur Herstellung von Polymerisationsprodukten des Vinylpyridins
Wie bereits vorstehend ausgeführt wurde, kommen in erster Linie die. Wärme- und die Emulsionspolyrnerisation in Frage. Letztere verdient den Vorzug im Fall der Herstellung von Mischpolymerisaten mit Dienen. Als Aktivatoren kommen die üblichen Stoffe in Frage. Ebenso- kann in Gegenwart von ScInvefel oder bekannten Stoffen, welche als Reak-. tionsregler dienen, gearbeitet werden.As already stated above, the. Heat and emulsion polymerization in question. The latter deserves preference in the Case of the production of copolymers with dienes. They come as activators usual substances in question. Likewise- can be in the presence of ScInvefel or known Substances which are classified as react. tion controller serve to be worked.
Als Vinylpyridiin@e kommen die a-, (3- und -(-Produkte sowie Homologe derselben in Frage.The a-, (3- and - (- products as well as homologues same in question.
Beispiel i In ioo Gewichtsteilen Vinylpyridin wird i Gewichtsteil Benzoylp,eroxyd gelöst. Man erwärmt alsdann etwa 6 Stunden auf 40°. Das se erhaltene Po@lyvinylpyridin stellt eine glasartige Mässe dar, welche beispielsweise mit Alkoph:olen oder Säuren vis.cose Lösungen gibt.Example i In 100 parts by weight of vinylpyridine there is 1 part by weight Benzoylp, eroxide dissolved. The mixture is then heated to 40 ° for about 6 hours. The se obtained Polyvinylpyridine is a glass-like measure, which, for example, with alcohols or acids, there are vis.cose solutions.
Beispiel 2 i oo Gewichtsteile Vinylpyridin werden unter Zugabe vori o,2 Gewichtsteilen Ammoniumpersulfat mit 18o Gewichtsteilen einer ioo;oigen Natriumoleatlösung emulgiert. Man erwärmt auf etwa 3o° und erhält nach 2o Stunden in go%iger Ausbeute das Polyvinylpyridin.Example 2 100 parts by weight of vinylpyridine are added with vori 0.2 parts by weight of ammonium persulfate with 180 parts by weight of a 100% sodium oleate solution emulsified. The mixture is warmed to about 30 ° and obtained after 20 hours in a good% yield the polyvinylpyridine.
Beispiel 3 8o Gewichtsteile Styrol und 2o Gewichtsteile Vinylpyridin werden mit 16o Gewichtsteilen' einer 2,5o;oi.gen. Lösung von isobutylniaphtbalin:sulfoisaurem Natrium unter Zusatz von 4 Gewichtsteilen. normaler Natronlauge und 0,2 Gewichtsteilen Ammoniumpersulfat emulgiert und etwa 2 Tage auf 55' unter Rühren erwärmt. Man erhält in quantitativer Ausbeute ein Polymerisat, welches mit Eisessig viscose Lösungen gibt, in veTdünnfier Essigsäure aber nicht mehr löslich ist, im Gegensatz zu den nach Beispiel i und 2 erhaltenen Polymerisaten.Example 3 80 parts by weight of styrene and 20 parts by weight of vinyl pyridine are with 16o parts by weight of a 2.5o; oi.gen. Solution of isobutylniaphtbalin: sulfoic acid Sodium with the addition of 4 parts by weight. normal caustic soda and 0.2 parts by weight Ammonium persulfate emulsified and heated to 55 'for about 2 days with stirring. You get in quantitative yield a polymer which is viscous with glacial acetic acid solutions there, but is no longer soluble in dilute acetic acid, in contrast to the according to Example i and 2 obtained polymers.
' Beispiel In einem Gemisch von 5o Gewichtsteilen Vinylpyridin und 25 Gewichtsteilen Styrol werden 0,3 Gewichtsteile Be-nzoylperoxyd gelöst. Man erwärmt etwa- io Stunden, auf 4o bis 5o°. Das so erhaltene Polymerisat gibt mit Eisessig viscose Lösungen, welche beliebig mit Wasser zu verdünnen sind. EXAMPLE 0.3 parts by weight of benzoyl peroxide are dissolved in a mixture of 50 parts by weight of vinyl pyridine and 25 parts by weight of styrene. It is heated to 40 to 50 ° for about 10 hours. The polymer obtained in this way gives viscous solutions with glacial acetic acid, which can be diluted with water as required.
Beispiel 5 75 Gewichtsteile Butadien und 25 Ge- wichtsteile Vinylpyridin werden mit 17o Gewichtsteilen einer 3;5o@oi:gen Lösung von isobutylnaphtbalinsulfo-saurem Natrium unter Zusatz von 3 Gewichtsteilen normaler Natronlauge und 0,3 Gewichtsteilen Ammoniumpersulfat bei etwa 30° emulgiert. Man bekommt nach etwa 9o Stundeneinen synthetischen Latex, :aus welchem nach der Koagulätion in einer Ausbeute von 750/0 ein kautschukähnliches Polymerisat von hervorragender Plastizität erhalten wird. Nimmt man statt 25 Gewichtsteilen Vinylpyridin 2o Gewichtsteile Styrol und 5 Gewichtsteile Vinylpyrid"m, so, erhält man unter sonst gleichen Bedingungen eine Ausbeute von 98% an Polymerisat. Ersetzt man das Vinylpyn-.din völlig durch Styrol, so sinkt die Ausbeute im sonst gleichen Ansatz und gleichen Zeiten auf etwa 45 %.Example 5 75 parts by weight of butadiene and 25 parts by weight of vinylpyridine with 17o parts by weight of 3; 5o @ oi: emulsified gen solution of isobutylnaphtbalinsulfo-sodium acid with addition of 3 parts by weight sodium hydroxide solution and 0.3 parts by weight of ammonium persulfate at about 30 °. After about 90 hours a synthetic latex is obtained from which, after coagulation, a rubber-like polymer of excellent plasticity is obtained in a yield of 750/0. If 20 parts by weight of styrene and 5 parts by weight of vinylpyridine are used instead of 25 parts by weight of vinylpyridine, a yield of 98% of polymer is obtained under otherwise identical conditions Approach and equal times to about 45%.
