Synthesis and Properties of some ɛ-Caprolactone-Based Di- and Triblock Polymers by Anionic Polymerization

An overview on the recent developments in reactive plasticizers in polymers

“…In addition, an endothermic peak at 54°C for PSt‐ g ‐PCL and 47°C for PVC‐ g ‐PCL corresponding to the melting temperature (Tm) of PCL segment. Because the PSt‐ g ‐PCL exhibit a single glass transition (Tg = 71°C), which is considerably lower than Tg of PSt‐N3, it could assume some miscibility between the PSt and PCL blocks . On the other hand, the presence of only one Tg of PVC‐ g ‐PCL lower than the Tg of PVC‐N 3 clearly indicates that PCL acts as a macromolecular plasticizer for the PVC …”

Synthesis, Characterization, Catalytic Reduction, and Splinting Activity of Poly(ε‐caprolactone–co–morpholine)/Ag Nanocomposite

“…Stannous octoate (SO)‐initiated ROP of ɛ‐caprolactone (CL) and morpholine (Mor) derivative mixtures was reported in the literature . The PCL based di‐ and triblock copolymers were reported by Buzdugan et al . An amphiphilic copolymer consists of dextran‐ b ‐PCL in an aqueous medium was reported by Zhang et al .…”

Synthesis of Multiblock Copolymers by Coupling Reaction Based on Self-Assembly and Click Chemistry

“…[6][7][8][9] In theory, multiblock copolymers could be synthesized by an alternately sequential addition of different comonomers into a living copolymerization system. [10][11][12] In practice, each addition of new monomer will inevitably make some living chains dead because of impurities, leading to the resultant block copolymer with lower block numbers and broad molecular weight distribution. Therefore, the sequential addition method can only be used to make copolymers with a few blocks, such as diblock or triblock copolymers.…”
