Biobased Hyperbranched Polyesters as Effective Non‐Leachable UV Blockers for Sunscreens

Macromolecular Materials and Engineering, EarlyView.
Three UV‐active hyperbranched polyesters are synthesized using lignin‐based monomeric molecules and potentially biobased hydandoin. These hyperbranched polymers show effective UV absorption in solution and blended creams. The blended creams show desirable photostability and negligible leakage into fresh or salt water, which indicates their potentially ...

Poly(amino acid) Synthesis from 2,5‐Diketopiperazines for Acid‐Actuated Drug Release

Macromolecular Materials and Engineering, EarlyView.
The ring‐opening polymerization (ROP) of 2,5‐diketopiperazines (2,5‐DKPs) to yield poly(amino acids) is reported. This route to poly(amino acids) has circularity, and permits the straightforward production of nanoparticles for controlled release applications.

On‐Resin Recycling of Acid‐Labile Linker Enables the Reuse of Solid Support for Fmoc‐Based Solid Phase Synthesis

Macromolecular Rapid Communications, EarlyView.
This study introduces the first recyclable and reusable resin for Fmoc‐based solid phase synthesis (SPS) of oligamide‐based structures through the regeneration of a cyclic acetal‐based linker on Tentagel resins. Even after multiple recycling and reuse cycles of the solid phase, consistently high yields and high‐purity products are obtained. Abstract In

Degradation strategies for structural characterization of insoluble synthetic polymers by mass spectrometry

Mass Spectrometry Reviews, EarlyView.
Abstract With the advent of soft ionization techniques such as electrospray (ESI) and matrix‐assisted laser desorption/ionization (MALDI) to produce intact gas‐phase ions from nonvolatile macromolecules, mass spectrometry has become an essential technique in the field of polymeric materials.
