Abstract

L'invention a trait à la polymérisation ou copolymérisation du chlorure de vinyle en présence d'aldéhydes comme agents de transfert de chaînes. On utilise comme agent de transfert un aldéhyde à substitution alcoyle dont, tout particulièrement, l'éthyl-2 hexanal. On obtient des polymères à PM contrôlé, de stabilité thermique améliorée et pratiquement exempts d'odeur aldéhydique.The invention relates to the polymerization or copolymerization of vinyl chloride in the presence of aldehydes as chain transfer agents. An alkyl-substituted aldehyde including, most particularly, 2-ethylhexanal, is used as transfer agent. Polymers with controlled MW, improved thermal stability and practically free of aldehyde odor are obtained.
