## Abstract Two novel tetra‐ and hexahydroxy functionalized perylene chromophores have been used as initiators for the Sn(oct)~2~ catalyzed ring‐opening polymerization of different lactones. The arms of the resulting star polymers were comprised of either crystallizable poly(L‐lactide) or poly(__ε_
Thermally cured polyurethanes were prepared from castor oil and hexamethylene diisocyanate (HMDI). Due to the long aliphatic chain of the castor oil component of polyurethane, thermal curing of castor oil based polyurethane (COPU) is limited by increasing polymer viscosity. To enhance further crossl
