Self-immolative polymers degrade by an end-to-end depolymerisation mechanism in response to the cleavage of a stabilizing end-cap from the polymer terminus. Examples include homopolymers, mixed polymers including block copolymers, suitable for a variety of applications. A polyglyoxylate can be end-capped or capped with a linker as in a block copolymer.

A fourth wheel: Two sets of bifunctional AB2C dendrimers having internal acetylene/azides and external hydroxy groups were constructed utilizing benign synthetic protocols. An in situ postfunctionalizationstrategy was successfully carried out to illustrate the chemoselective nature of these dendrimers. The dendrimers were also transformed into dendritic nanoparticles or utilized as dendritic crosslinkers

Azide terminally functional poly(methyl methacrylate)s (Mn
= 4000â6000, PDI = 1.21â1.28) have been prepared by living radical polymerization and successfully reacted with alkynes in a Huisgen cycloaddition (click) reaction in one pot using the same catalyst for both processes.

Biodegradable aliphatic polyesters such as polylactide (PLA) are widely used in medical applications. When employed as an implantable material, the control of the surface properties of PLA is of great interest because biochemical reactions occur on the surface or at interfaces. Thus, chemicalmodifications of the surface of degradable polyesters can be used to tailor the surface properties while preserving the

-type miktoarm star polymers with steroid core via a combination of “Click” chemistry and ring opening polymerization techniques
Well‐defined AB3‐type miktoarmstar‐shaped polymers with cholic acid (CA) core were fabricated with a combination of “click” chemistry and ringopeningpolymerization (ROP) methods. Firstly, azide end‐functional poly(ethylene glycol) (mPEG), poly(methyl methacrylate) (PMMA), polystyrene (PS), and poly(ε‐caprolactone) (PCL) polymers were prepared via controlled polymerization and chemical modification
