Synthesis via RAFT Polymerization of Tadpole-Shaped Organic/Inorganic Hybrid Poly(acrylic acid) Containing Polyhedral Oligomeric Silsesquioxane (POSS) and Their Self-assembly in Water
Abstract
Tadpole-shaped inorganic/organic hybrid poly( tert -butyl acrylate) was prepared by RAFT polymerization of tert -butyl acrylate ( t BA) using a POSS-containing chain transfer agent (CTA). The polymerization kinetics showed a pseudofirst-order behavior with a short induction period; the number-average molecular weights linearly increase with conversion. In conjunction with low polydispersity (PDI < 1.3), this confirms a controlled polymerization. POSS-P t BA was further hydrolyzed into amphiphilic, tadpole-shaped poly(acrylic acid) (POSS-PAA). The self-assembly behavior of POSS-PAA in aqueous solution at pH = 8.5 was investigated by transmission electron microscopy (TEM) as well as static and dynamic light scattering (SLS and DLS). The results show that POSS-PAA self-assembles in water into rather large aggregates where the POSS moieties are dispersed in the particle. The size (average radius ≈ 60 nm by DLS) is nearly independent of the chain length of PAA. The aggregates are pH-responsive, contracting when decreasing pH from 8.5 to 4.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
