Description
Verfahren zur Herstellung von Mischpolymerisaten Es wurde gefunden, daß man technisch besonders wertvolle Mischpolymerisate durch Polymerisation von Mischungen aus Styrol oder dessen Homologen bzw. Derivaten und Estern der Acrylsäure oder deren Homologen mit aliphatischen Alkoholen mit mindestens 4. Kohlenstoffatomen erhält, wenn man Mischungen verwendet, die auf ioo Teile Styrolkörper nur etwa a bis io, vorzugsweise etwa 5TeileAcrylsäureester@enthalten. DieBolymerisation dieser Mischungen kann nach an sich bekannten Verfahren erfolgen, beispielsweise in Substanz oder wässeriger Emulsion in kontinuierlicher oder diskontinuierlicher Arbeitsweise.Process for the production of copolymers It has been found that one industrially particularly valuable copolymers by polymerizing Mixtures of styrene or its homologues or derivatives and esters of acrylic acid or their homologues with aliphatic alcohols with at least 4th carbon atoms obtained when using mixtures which contain only about a to 10, preferably about 5 parts of acrylic acid ester @. The polymerization of these Mixtures can be carried out by processes known per se, for example in bulk or aqueous emulsion in continuous or discontinuous operation.
Als Homologe bzw. Derivate des Styrols kommen beispielsweise in Frage Methylstyrole und Chlorstyrole. Geeignete Ester der Acrylsäure sind beispielsweise der Acrylsäuren-butylester, -isobutylester, -amylester, -octylester usw. i auch die entsprechenden Ester der a-Methylacrylsäure kommen beispielsweise als Ausgangsmaterial in Betracht.Possible homologues or derivatives of styrene are, for example Methyl styrenes and chlorostyrenes. Suitable esters of acrylic acid are, for example the acrylic acid butyl ester, isobutyl ester, amyl ester, octyl ester, etc. i also the corresponding esters of α-methylacrylic acid are used, for example, as starting material into consideration.
Die erhaltenen Mischpolymerisate besitzen gegenüber den aus Styrol allein hergestellten Polymerisaten den Vorzug der größeren Elastizität bei Zimmertemperatur und den der höheren - Zähigkeit bei erhöhten Temp:ergturen. Letzteres ist beispielsweise für das Verarbeiten der Mischpolymexis'ate nach dem Spritzverfahren von großer Wichtigkeit. Gegenüber den Mischpolymerisaten aus Styrol und größeren Mengen Acrylsäurebutylestex besitzen die gemäß der Erfindung erhältlichen speziellen Mischpolymerisate insbesondere den Vorzug der größeren Härte. Die neuen Mischpolymerisate kommen z. B. für die Herstellung von Spritzmassen in Frage und liefern hierbei Formkörper, bei denen Spannungsrisse nicht auftreten.The copolymers obtained have compared to those made of styrene Polymers produced alone have the advantage of greater elasticity at room temperature and that of the higher - toughness at increased temp: ergturen. The latter is for example of great importance for processing the mixed polymers by the injection molding process. Compared to the copolymers made of styrene and larger amounts of butyl acrylate the special copolymers obtainable according to the invention have in particular the advantage of greater hardness. The new copolymers come z. B. for the Production of injection molding compounds in question and hereby deliver moldings in which Stress cracks do not occur.
