Haddleton (1273797) Polymers Amphiphiles Copper catalysts Chemical bonds Polymerization Migrated from ePrints The lower limit of domain size resolution using microphase separation of short poly(acrylic acid) homopolymers equipped with a short fluorinated tail, posing as an antagonist ‘A block’ in pseudo AB block copolymers has been investigated. An alkyl halide initiator with a fluorocarbon chain was utilized as a first ‘A block’ in the synthesis of low molecular weight polymers (1400–4300 g mol−1) using photoinduced Cu(II)-mediated polymerization allowing for very narrow dispersity. Poly(tert-butyl acrylate) was synthesized and subsequently deprotected to give very low degrees of polymerization (N), amphiphilic polymers with low dispersity (Đ = 1.06–1.13). By exploiting the high driving force for demixing and the well-defined ‘block’ sizes, we are able to control the nanostructure in terms of domain size (down to 3.4 nm full-pitch) and morphology. This work demonstrates the simple and highly controlled synthesis of polymers to push the boundaries of the smallest achievable domain sizes obtained from polymer self-assembly.<br><br>The files detailing experimental results are organised by technique used for the characterisation of the final products in folders: DSC: differential scanning calorimetry GPC-SEC: Gel permeation chromatography-size exclusion chromatography MALDI: Matrix-Assisted Laser Desorption/Ionization NMR: Nuclear Magnetic Resonance SAXS: small-angle x-ray scattering TEM: transmission electron microscopy --> Software needed to open files according to technique used: for NMR files: ACD-LABS for MALDI-ToF files: Excel, Bruker Data Analysis for GPC files: Agilent GPC for SAXS: EDF Viewer (Foxtrot) for DSC: Excel for TEM: DigitalMicrograph (GMS 3) 2019-11-12T00:00:00Z Dataset Dataset 10.82444/warw.33795271.v1 https://figshare.com/articles/dataset/Data_for_Microphase_separation_of_highly_amphiphilic_low_N_polymers_by_photoinduced_copper-mediated_polymerization_achieving_sub-2_nm_domains_at_half-pitch/33795271 CC BY 4.0
