The iniferter method was studied for the synthesis of polyvinyl block copolymers of relatively low mol. weight using tetramethylthiuram disulfide (I) and benzyl diethyldithiocarbamate (II) as initiator. Considering the low quantum yield of dissociation (ϕd) of I (2.5·10-3 in cyclohexane), I was used as a thermal initiator (95°) for the synthesis of dithiocarbamate-polystyrene telechelics. 13C-NMR anal. of these telechelics showed 2 13C=S signals corresponding to 2 different end groups: Et2NCSS2CHPhCH2– and Et2NCSS2CH2CHPh-. Several styrene polymerizations were also carried out in the presence of AIBN as thermal initiator and I as chain-transfer agent. Depending on the AIBN-I mole ratio, mono- and difunctional telechelics were formed, as evidenced by NMR anal. These telechelics were used for the photochem. initiations of Et acrylate (III), acrylic acid, and Me methacrylate (IV). It was assumed that ϕd of the dithiocarbamate end group was equal to that of II (0.06). Nonfunctional polymers were also prepared, either photochem. by dissociation of II, or thermally in presence of AIBN and II as transfer agent. They were used for block copolymerization with IV. Inversely, telechelics were prepared in a first step; in this case ϕd = 0.026. They were then used for the polymerization of III. The block copolymers were fractionated; their composition and mol. weights were determined by 1H NMR and gel-permeation chromatog., resp.
