All acrylic-based thermoplastic elastomers with high upper service temperature and superior mechanical properties

Abstract

All acrylic-based thermoplastic elastomers (TPEs) offer potential alternatives to the widely-used styrenic TPEs.

Block Copolymers: Synthesis, Self-Assembly, and Applications

“…In comparison with diene-based TPEs, all acrylic-based TPEs showed higher oxidation stability and UV resistance. The same group synthesized a series of TP all acrylic-based high temperature thermoplastic elastomers containing poly(1-adamatyl acrylate) as a hard domain and poly(tetrahydrofurfuryl acrylate) as a soft domain by RAFT polymerization [ 93 ]. These TPEs exhibited superior stress-strain behavior compared to that of conventional all acrylic-based TPEs consisting of PMMA and PBA made by controlled radical processes [ 94 ], while the tensile strength was lower compared to that of similar products prepared via living anionic polymerization [ 95 ].…”

Photo-curable poly-(ethylene glycol)–fumarate elastomers with controlled structural composition and their evaluation as eluting systems

“…where M wp is the M w of the pre-polymer and M wm is the M w of the repeating unit. 1 Fourier transform infrared (FTIR) spectra were obtained with a Shimadzu 8201 PC apparatus.…”

“…The radical mediated cross-linking reactions of (met)acrylic acid esters and related compounds are well known processes, traditionally used for the preparation of thermosets and various resins. 1 Related a,b-unsaturated carboxylic acids, such as fumaric and maleic acid, have also been used for the preparation of resins and thermosets. Given that the structure of these monomers can lead to unfavorable curing kinetics, they are usually co-polymerized with other vinyl monomers.…”

RAFT polymerisation of renewable terpene (meth)acrylates and the convergent synthesis of methacrylate–acrylate–methacrylate triblock copolymers

“…This behaviour is typical of polyacrylate materials which generally exhibit a higher chain entanglement length than some other typically used soft blocks (such as polybutadiene or polyisoprene), which in turn reduces the density of entanglements in the soft matrix. 52 The films of αBα-74-23 used in the tensile measurements were observed to adhere well to many substrates, and the tack was observed to be lasting. This is not surprising as this type of soft, acrylic TPE material is well-suited for use as a PSA, and can offer improvement over some of the more common types.…”
