Polymeric Nanoparticles for the Modification of Polyurethane Coatings
… and radical reaction upon the decomposition of a photo-initiator under UV radiation. Both methods allow retaining the spherical shape of the micelles leading to narrowly distributed non fusible nanospheres. In the case of B-M nanoparticles, the degree of cross-linking seemed independent of the …

Functional Triblock Terpolymers for Multicompartment Micelle and Janus Particle Synthesis
… (THF) with sec-butyllithium (sec-BuLi) as initiator. Poly(p-tert-butoxystyrene) (PtS) was hydrolyzed to poly(p-hydroxystyrene) (PHS) which is water-soluble at high pH values, opening the possibility to prepare water-soluble JPs. The pH-responsive behavior of …

DEVELOPMENT OF SYNTHETIC POLYMERS FOR BONE TISSUE ENGINEERING: ENGINEERING THE DEGRADATION RATE
… to micro sized fibers was developed using the photo initiator bis(2,4,6-trimethybenzoyl) phenoylphosphine oxide (BAPO) to crosslink the fumarate-based fibers in situ while electrospinning. Characterization showed that the alterations to the general electrospinning technique could be used to …

Reversibly Photo-Crosslinkable Polycarbonate-Based Polymersomes for Drug Encapsulation and Delivery
… pendant coumarin groups. Coumarin groups undergo photo-reversible dimerization when irradiated with specific ultraviolet wavelengths, so they can be used to prepare polymers with photo-responsive properties. In this case, the pendant coumarin groups enable stabilization of the polymersome membrane …
