A modular approach for the design of two-component supramolecular polymer (SMP) networks is reported. series materials was prepared by blending two (macro)monomers based on trifunctional poly(propylene oxide) (PPO) cores that were end-functionalized with hydrogen-bonding 2-ureido-4[1H]pyrimidinone (UPy) groups. One monomer a PPO core number-average molecular weight (Mn) 440 g mol-1. The SMP formed this building block glassy, brittle material glass transition temperature (Tg) about 86 °C....
Abstract Due to their low melt viscosity, competitive adhesive properties, and the stimuli‐responsive nature of supramolecular interactions, various polymers have recently been investigated as adhesives with on‐demand (de)bonding capability. The properties a series hydrogen‐bonded polymer networks based on telechelic poly(ethylene‐ co ‐butylene) (PEB) terminated isophthalic acid (IPA) groups bifunctional pyridines (Py) are reported herein. These microphase segregate into an IPA‐Py rich hard...
A growing body of work shows that the phase behavior supramolecular polymers assembled from telechelic building blocks featuring binding motifs at two termini is quite similar to conventional block copolymers. However, it remains unclear how crystallization formed by motifs, which occurs in many polymers, affects morphology such materials. Here we report a systematic investigation series based on poly(ethylene-co-butylene) (PEB) telechelics and complementary H-bonding pair isophthalic...
