## Abstract Spirocyclic tin dialkoxides are unique initiators for the ring‐expansion polymerization of lactones leading to complex, but well‐defined macromolecular architectures. In a first example, ε‐caprolactone (εCL) was polymerized, followed by the resumption of polymerization of a mixture of ε
## Abstract **Summary:** Water‐soluble, partially hydrophobized derivatives of __O__‐(carboxymethyl)cellulose (CMC) were prepared by esterification of CMC in its ‘gel suspension’ form. The classical esterification method (A) using stearoyl chloride/pyridine as well as two unconventional methods bas
