Processability and characterization of poly(vinyl chloride)-b-poly(n-butyl acry...
Coelho, Jorge F. J.; Carreira, Mafalda; Gonçalves, Pedro M. O. F.; Popov, Anatoliy V.; Gil, Maria H.This work reports the synthesis and processing of a new flexible material based on PVC produced by living radical polymerization. The synthesis was carried out in a two-step process. In the first step the macroinitiator alpha, omega-di(iodo)poly(butyl acrylate) [alpha, omega-di(iodo)PBA] was synthesized in water by single electron transfer/degenerative chain transfer mediated living radical polymerization (SET-...
Single electron transfer-degenerative chain transfer living radical polymerizat...
Coelho, Jorge F. J.; Silva, Ana M. F. P.; Popov, Anatoliy V.; Percec, Virgil; Abreu, Mariana V.; Gonçalves, Pedro M. O. F; Gil, M. H.Living radical polymerization of n-butyl acrylate was achieved by single electron transfer/degenerative-chain transfer mediated living radical polymerization in water catalyzed by sodium dithionate. The plots of number-average molecular weight versus conversion and ln[M]0/[M] versus time are linear, indicating a controlled polymerization. This methodology leads to the preparation of alpha,omega-di(iodo) poly (b...

Coelho, Jorge F. J.; Silva, Ana M. F. P.; Popov, Anatoliy V.; Percec, Virgil; Abreu, Mariana V.; Gonçalves, Pedro M. O. F.; Gil, M. H.The synthesis of a block copolymer poly(vinyl chloride)-b-poly(n-butyl acrylate)-b-poly(vinyl chloride) is reported. This new material was synthesized by single-electron-transfer/degenerative-chain-transfer-mediated living radical polymerization (SET-DTLRP) in two steps. First, a bifunctional macroinitiator of alpha,omega-di(iodo)poly (butyl acrylate) [alpha,omega-di(iodo)PBA] was synthesized by SET-DTLRP in wa...
