Latex Serum‐Derived Supramolecular Networks Enable Toughening of Natural Rubber

Macromolecular Rapid Communications, EarlyView.
Latex‐serum addition enhances strain‐induced crystallization (SIC) toughening in natural rubber, increasing tearing strength and extending the SIC activation window. Supramolecular networks form via bifurcated hydrogen bonding between polyol components (e.g., quebrachitol) and end‐functionalized polyisoprene chains, serving as effective crystallization

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents

Polymer International, EarlyView.
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐
