A precursor polymer has been designed on the basis of an idea of conversion of hyperbranched polymer to an inorganic substance by lithographic procedure. For this purpose hyperbranched polyethoxysiloxane (PEOS) was synthesized via a one-pot catalytic condensation reaction of tetraethoxysilane with acetic anhydride. PEOS was modified with cyclohexanol via a catalytic trans-esterification reaction....
Poly(methyl methacrylate) (PMMA) nanogels cross-linked with cyclodextrin-methacrylate (CD-MA) are synthesized by surfactant-free precipitation polymerization. α-, β- and γ-cyclodextrins (CD) are functionalized with methacrylic groups (CD-MAs) with an average amount of vinyl bonds per CD molecule of 2, 4, or 6, and they are used as cross-linker and as complexation unit. The formation and the particle...
In this work, the incorporation of reactive cyclodextrins (CDs) in aqueous nanogels based on poly(N-vinylcaprolactam) (VCL) is studied by surfactant-free precipitation polymerization process. α-, β-, γ-CDs were functionalized with acrylic groups and the average amount of vinyl bonds per CD molecule was adjusted to 2, 4, or 6. The increase of the CD concentration in the reaction mixture led to the...
Anionic polymerization of EEGE with alkali metal based initiators has been shown to yield polyglycidol with low polydispersity indices for molecular weights up to M n ≈30,000. Higher molecular weights have not been obtained due to the occurrence of a chain transfer reaction to the monomer. Chain transfer to the monomer leads to P(EEGE) with an alcohol end group and an allylic alcoholate, which...
