## Abstract
|
||
|
||
Cationically charged bottlebrush copolymers were produced by hydrolysis of poly(2-ethyl-2-oxazoline) (PEtOx). The cationic ring-opening polymerization of EtOx was initiated using a styrene derivative to produce PEtOx macromonomers with two different lengths. After detailed characterization, these macromonomers were polymerized via reversible addition-fragmentation chain transfer (RAFT) polymerization in a grafting-through process. The length of the bottlebrush backbone was varied, and it was found that a good control over the polymerization could be retained up to backbone DP 50. Hydrolysis of PEtOx repeating units under acidic conditions afforded cationic bottlebrushes, with a defined charge content that could be adjusted by changing the hydrolysis reaction time. Bottlebrush copolymers were analyzed in detail using size-exclusion chromatography, small-angle neutron scattering, and atomic force microscopy indicating a cylindrical topology and an increasing flexibility with increasing chain length.

## Come è citata nella tesi
|
||
|
||
- **Sez. 4.3 Polimeri bottle brush** (`tesi.md` r. 1060): Al contrario, aumentando il peso molecolare dei segmenti laterali (ad esempio stimando tre catene per lato, per un peso teorico atteso di circa 62000 Da), la drastica compattazione strutturale porta a una sottostima del peso reale che si aggira intorno al 70%.[57]
