Zn(OAc) 2 β’2H 2 O is found to be an effective bulk polymerization catalyst for the ring-opening polymerization of rac-lactide, l-lactide, -caprolactone and β¦-valerolactone. The propensity of polymerizations can be enhanced by performing them in the presence of appropriate amounts of different alcoho
A very convenient synthetic method is described for the known cyclic aryloxyphosphazenes [N3P3(OC6H4-R)6] (R = Br, CN, CHO, COCH3, COC6H5, and NO,). The method is based on the direct reaction of [N3P3C16] with six equivalents of the para-substituted phenols HOC6H4-R and K&03 in refluxing acetone and
