Abstract: The synthesis of nanoparticles based on hyperbranched-linear-hyperbranched ABA triblock copolymers with hyperbranched polyglycerol (hbPG) as A-block and linear poly(oxymethylene) as B-block is described. The acid-degradable nanoparticles were formed in a facile process, combining a solvent evaporation process with the miniemulsion technique resulting in particles with a diameter in the range of 190 to 250 nm and a standard deviation of ˜30% determined with DLS and SEM. The nanoparticles were placed on a silicon wafer and sintered leading to films with a thickness in the ?m-range investigated via SEM. The surface properties of these films were investigated via static contact angle measurements at the liquid/vapor interface. The contact angle decreases from 67° for the polymer with two hydroxyl groups to 29° for the polymer with 16 hydroxyl groups, confirming the influence of the polymer structure and size of the hbPG block on the surface properties.

Abstract: Synthesis of hyperbranched-linear-hyperbranched ABA triblock copolymers based on linear poly(oxy methylene) (POM) and hyperbranched poly(glycerol) (hbPG) blocks is described. The polymers having a polyacetal polyether structure were prepared from linear bishydroxy functional POM macroinititators, obtained by cationic ring-opening polymerization of trioxane and dioxane with formic acid as transfer agent and following hydrolysis of the formiate group. Partial deprotonation of the resulting hydroxyl groups permitted the hypergrafting by anionic ring-opening multibranching polymerization (ROMBP) of glycidol.
