Abstract
AbstractNitroxide mediated polymerization (NMP) of methacryloisobutyl POSS (POSSMA) was conducted in a dispersed aqueous miniemulsion at 90°C, resulting in stable latexes with particle sizes = 225–260 nm at solids loading = 22%. POSSMA homopolymers with up to 35.9 kg mol−1 (Đ < 1.53) was prepared using Dispolreg 007 alkoxyamine without any controlling comonomers, as is traditionally required for NMP of methacrylates. Copolymers with different ratios of POSSMA and bio‐based C13 methacrylic esters were also synthesized (monomer conversion [X] up to 96.5% and 1.42 < Đ < 1.68) to prepare polymer resins with a wide range of glass transition temperatures (Tg) or melting points (Tm) (−30°C < Tg, Tm < 96°C). The resulting homopolymers and copolymers exhibited semi‐crystalline properties, with crystallite size of 20.3–44.4 Å.
