Title: Non‐Tacky Fluorinated and Elastomeric STEM Networks

Journal Article · · Macromolecular Rapid Communications

Abstract Soft, elastomeric, non‐tacky polymer networks are synthesized by reversible deactivation radical polymerization (RDRP). First, the pristine, structurally tailored and engineered macromolecular (STEM) networks are synthesized by reversible addition–fragmentation chain transfer (RAFT) polymerization and incorporated an atom transfer radical polymerization (ATRP) inimer into the network. Subsequently, poly( n ‐butyl acrylate) (PBA) and/or poly(octafluoropentyl acrylate) (POFPA) side chains are grafted from the network by photo‐induced ATRP. These low glass transition temperature side chains produced soft materials ( E  = 104–178 kPa). However, only the POFPA‐containing networks are also non‐tacky. The fluorine content and material properties are investigated by dynamic mechanical analysis, elemental analysis, spectroscopy, and contact angle measurements.
