Soft and rigid core latex nanoparticles prepared by RAFT-mediated surfactant-free emulsion polymerization for cellulose modification – a comparative study†

Latex nanoparticles comprising cationically charged coronas and hydrophobic cores with different glass transition temperatures (Tg) have been prepared by surfactant-free, RAFT-mediated emulsion polymerization, where the particles form through a polymerization-induced self-assembly (PISA) type mechanism. Poly(2-dimethylaminoethyl methacrylate-co-methacrylic acid) (P(DMAEMA-co-MAA)) was utilized ...

Model Predictive Control of Free Surfactant Concentration in Emulsion Polymerization

Abstract: In emulsion polymerization processes, the surfactant concentration plays an important role in the latex stability, reaction kinetics and particle size distribution (PSD). Controlling the free surfactant concentration in the aqueous phase ensures the stability of the latex and the control of the micellar nucleation rate. The PSD is determined by particle nucleation, growth and stabilit...

Preparation of Inert Polystyrene Latex Particles as MicroRNA Delivery Vectors by Surfactant-Free RAFT Emulsion Polymerization.

We present the preparation of 11 nm polyacrylamide-stabilized polystyrene latex particles for conjugation to a microRNA model by surfactant-free RAFT emulsion polymerization. Our synthetic strategy involved the preparation of amphiphilic polyacrylamide-block-polystyrene copolymers, which were able to self-assemble into polymeric micelles and "grow" into polystyrene latex particles. The surface ...

Effect of Concentration of Surfactant and Additive on Morphology of Polyaniline Nanocomposites Prepared in Aqueous Solution

In this work polyaniline nanocomposites were synthesized in aqueous media by using ammonium proxy disulfat (APS) (10g/l) as an oxidant in the presence of hydroxy propyl cellulose (HPC) (2,5,10 g/l) as a surfactant, poly (vinyl chloride) (10,30 g/l) as an additive and sulfuric acid (H2SO4). The effects of concentration of surfactant and additive on morphology have been ...
