Innovative heterofunctional monomers: cyclobutene inimers

Innovative heterofunctional monomers: cyclobutene inimers

Well-defined high molar mass poly(1,4-butadiene)-g-polyesters have been designed either through the grafting from or the grafting through route by the combination of ring-opening metathesis polymerization (ROMP) and organocatalyzed ring-opening polymerization (ROP) of L–lactide (LA) and e-caprolactone (e-CL). Both methodologies provide poly(1,4-butadiene)-g-polyesters having a strictly poly(1,4-butadiene) backbone. Use of the grafting from strategy allowed the synthesis of poly(1,4-butadiene)-g-poly(e-caprolactone) (PBu-g-PCL) with the highest molar mass ever reported. Furthermore, in the solid state upon isothermal crystallization at room temperature, PCL side chains fold while they form an orthorhombic molecular network, building up a self-assembled lamellar phase with large scale d-spacing’s.
