Guegain, Elise published the artcileRadical Ring-Opening Copolymerization-Induced Self-Assembly (rROPISA), Product Details of C16H30O2, the main research area is radical ring opening copolymerization induced self assembly.
Radical ring-opening copolymerization-induced self-assembly (rROPISA) was performed by copolymerizing benzyl methacrylate and cyclic ketene acetals (CKA), such as 2-methylene-4-phenyl-1,3-dioxolane or 5,6-benzo-2-methylene-1,3-dioxepane, in heptane at 90 °C by reversible addition-fragmentation chain transfer (RAFT) polymerization from a poly(lauryl methacrylate) macro-RAFT agent. The chain lengths of both the solvophilic macro-RAFT agent and the solvophobic block, together with the initial amount of CKA, were independently varied to achieve various compositions The amount of CKA in the copolymers ranged from 4 to â?0 mol % by adjusting the monomer stoichiometry, leading to nearly complete degradation for CKA contents above â?5 mol %. rROPISA led to stable nanoparticles in all cases, ranging from 40 to 500 nm in diameter, depending on the exptl. conditions, as assessed by dynamic light scattering and transmission electron microscopy. Low average diameters and very narrow particle size distributions were obtained for CKA contents below 20 mol %, except for a targeted solvophobic chain length of 300 that gave narrow particle size distributions up to 50 mol % in CKA. Morphol. investigation revealed the formation of spheres for all copolymer compositions, which was assigned to both the nature of the RAFT agent used and insertion of CKA in the solvophobic block, which prevent the formation of other morphologies.
