“…However, even a very little amount of sodium salt in eopolymers [5] led to a noticeable increase of their thermal resistance. The thermal stability of zinc -containing copolymers [4] increased clearly with increasing zinc acrylate content up to 22.6 mole %. Small amounts of A2Co, A2Ni and A2Cu improved the thermal resistance of eopolymers [4], which then gradually dropped at higher eoneentrations of the salts.…”

Small amounts of A2Co, A2Ni and A2Cu improved the thermal resistance of eopolymers [4], which then gradually dropped at higher eoneentrations of the salts. When the nickel acrylate content is about 10 mole %, the decomposition temperatures of the copolymers are about 25 ~ lower than those of polystyrene.…”

“…When the nickel acrylate content is about 10 mole %, the decomposition temperatures of the copolymers are about 25 ~ lower than those of polystyrene. The experimentally found thermal stability of styrene copolymers containing different metal acrylates [4,5] corresponds to those of the respective poly(metal acrylates) [2,3]. However, the thermal behaviour of the maeromolecules cannot be correlated with any specific property of the metals.…”

“…The thermal behaviour of some transition metal acrylate-styrene copolymers [4] and eopolymers of styrene with lithium, sodium and potassium acrylates and methacrylates [5] has also been investigated. In extension of these studies, the present paper is concerned with the thermal stabilities of styrene copolymers with magnesium, calcium, strontium and barium acrylates obtained in a process of a direct copolymerization.…”

The glass transition temperatures of styrene copolymers containing different amounts of Zn(II), Co( 11) and Ni( 11) acrylates were determined by differential scanning calorimetry. Based on these data the T, values of the polyacrylates were estimated b y the extrapolation method. The observed dependences of T, on copolymer composition could be described satisfactorily by the KWEI equation. It may be concluded that in all systems ionic crosslinking of similar efficacy occurs. Glasiibergangstemperaturen yon Copolymeren des Styrens rnit Zn(ZZ)-, Co(IZ)-und Ni(ZI)-AcrylatenDie Glasiibergangstemperaturen von Styrencopolymeren mit unterschiedlichen Anteilen an Zn( 11)-, Co( 11)-, und Ni( 11)-Acrylaten wurden rnit Hilfe der Differential-Scanning-Calorimetrie bestimmt. Auf der Grundlage dieser Ergebnisse wurden die Glasiibergangstemperaturen der Polyacrylate durch Extrapolation abgeschatzt. Die beobachteten Abhangigkeiten der Glasiibergangstemperaturen von der Zusammensetzung der Copolymere konnten befriedigend mit der von KWEI angegebenen Beziehung beschrieben werden. Hieraus wird geschlossen, daS in allen untersuchten Systemen eine ionische Vernetzung rnit vergleichbarer Wirksamkeit auftritt.
