## Abstract Mixtures of RZnCl and __t__BuCl (R = Et) initiate the polymerization of isobutene in the temperature range of (−35)—(+35) °C. The order of addition of the reagents is important for effective polymerization. Increasing the solubility of the zinc reagent (R = __n__‐octyl) and use of cumyl

Zn(OAc) 2 •2H 2 O is found to be an effective bulk polymerization catalyst for the ring-opening polymerization of rac-lactide, l-lactide, -caprolactone and ␦-valerolactone. The propensity of polymerizations can be enhanced by performing them in the presence of appropriate amounts of different alcoho
## Abstract Poly(L‐lactide)‐__block‐__poly(L‐amino acids) __block__ copolymers were prepared via polymerization of α‐amino acid __N__‐carboxyanhydrides with amino‐terminated poly(L‐lactide)s as macroinitiators. Two types of macroinitiators were used, one with an aminopropoxy head group (number‐aver
