Bulk grafting of decyl methacrylate onto poly(vinyl chloride) in the presence of a lead carboxylate stabilizer

Abstract

In order to improve the permanence of the plasticizer in a poly(vinylch1oride) (PVC) compound we have studied the free radical polymerization and grafting of decyl methacrylate (DMA) onto PVC in the presence of a lead stabilizer. The influence of different parameters has been investigated and homogeneous PVC-g-PDMA copolymers have been obtained. Their molecular weights and the glass transition temperatures were consistent with the grafted nature of the copolymers. ZUSAMMENFASSUNGUm die Weichmacherpermanenz in PVC zu verbessern, wurde Decylmethacrylat (DMA) in Gegenwart eines Bleistabilisators (LS) mittels radikalischer Polymerisation auf PVC gepfropft. Die Molekulargewichte und Glastemperaturen der erhaltenen Produkte bestltigten, d& homogene PVC-g-PDMA-Copolymere entstanden waren.
