Supramolecular silicone elastomer is a promising material for sustainable development. Here, quadruple hydrogen bonded ureidopyrimidinone (UPy) units were grafted onto high molecular weight polydimethylsiloxanes (PDMS), providing a novel supramolecular silicone elastomer. The high molecular weight PDMS precursor was prepared through a cyclic trimeric phosphazene base catalyzed ring‐opening polymerization of Octamethylcyclotetrasiloxane (D4) and tetravinyltetramethylcyclotetrasiloxane (V4) with a well‐controlled vinyl content. Its side chains were modified by hydroxyl groups via a thiol‐ene reaction. Then UPy units were further grafted on the side chain of high molecular weight PDMS by the isocyanate‐hydroxy reaction. The mechanical and self‐healing properties of the elastomer can be controlled by adjusting the molecular weight of PDMS and the amount of UPy units. The obtained PDMS elastomers displayed excellent stretchability (elongation at break of 1513%), good self‐healing efficiency (76% at 60°C for 2 h), and high resilience (elastic recovery of 93% under 300% strain cyclic stretching).

The commercially available 1,2-polybutadiene (1,2-PB) contains highly reactive CC bonds and has excellent machinability, which is an ideal raw material for preparing thermoplastic elastomers. The preparation of supramolecular cross-linked 1,2-PB thermoplastic elastomer with good recyclability and excellent mechanical properties has promising applications. Here, the 1,2-PB elastomers (UPB elastomers) were prepared by conjugating a few percent 2-ureido-4[1H]-pyrimidinone (UPy) self-complementary quadruple hydrogen bonding units onto the high molecular weight (M n) 1,2-PB chains via the thiol-ene click reaction. The used 2-(mercaptoethyl-ureido)-pyrimidinone derivative (UPy-SH) with a branched alkyl group had good compatibility with 1,2-PB in organic solvent contributing to a high transparency of recyclable UPB elastomers. The cross-linking density of UPB elastomers can be conveniently adjusted by varying the UPy content, which ultimately determined the mechanical properties of resulting supramolecular elastomers. Abundant chain entanglements formed by 1,2-PB chains with a high M n of 455 kDa and strong quadruple hydrogen bonding networks formed by side UPy units endowed UPB elastomers with excellent mechanical properties and damping properties. It was found that sample UPB-2 containing 2 mol % UPy units showed a tensile strength of 13.4 MPa, a high elongation at break of 1167%, a high elastic recovery of 89% (under large tensile deformation of 400%), a high peak tan δ value (tan δmax) of 1.4, and an effective damping temperature range width of 30.6 °C. Moreover, UPB elastomers have good recyclability given the noncovalent cross-linking networks. This effective and universal strategy provides some insights into the design of physically cross-linked high-performance 1,2-polybutadiene elastomers.

“…Furthermore, the side chain of the MVQ is connected with methyl and vinyl groups via silicon atoms, thus making it both inorganic and organic reactive. The above characteristics make silicone rubber outperform ordinary organic rubber in heat, weather, abrasion and ozone resistance, chemical stability, and electrical insulation 30,31 …”

A new series of thermoplastic elastomers were fabricated in this study employing ethylene‐octene copolymer (POE) and methyl vinyl silicone rubber (MVQ) as the thermoplastic phase and the elastomeric phase, respectively. The effect of POE/MVQ blending ratios on the vulcanization, mechanical, and thermal properties, cold resistance, shape memory properties, and hydrophobicity of the thermoplastic composites was investigated. Moreover, specific properties such as low‐temperature impact (LTI), shape memory and hydrophobicity properties exhibited by the POE/MVQ thermoplastic composites were studied in detail. The results indicated that the POE/MVQ composites exhibited remarkable mechanical properties and LTI strength. With the MVQ content reaching 10 phr, their tensile strength reached 30.07 MPa, significantly higher than that of pure POE. Regarding shape memory properties, the shape fixing ratio and the shape recovery ratio were 97.6% and 94.3%, respectively, at the MVQ content of 40 phr.
