Solid state polymerization
TL;DR: In this article, an improved process for solid state polymerizing a polyester prepolymer into a high molecular weight polyester resin was proposed, in which the vapor of at least one member selected from the group consisting of volatile chlorinated hydrocarbons, volatile ketones, tetrahydrofuran, ethylene oxide, and propylene oxide was used.

Enzyme-catalyzed ring-opening polymerization of unsubstituted beta-lactam
TL;DR: The synthesis of poly(beta-alanine) by Candida antarctica lipase B immobilized as novozyme 435 catalyzed ring-opening of 2-azetidinone is reported, and the formation of the polymer is confirmed with (1)H NMR spectroscopy and MALDI-TOF mass spectrometry.

TL;DR: The structure/reactivity relationship study revealed that (OMe2)TPT, being both a strong nucleophile and a good leaving group, exhibits the highest HTP activity and also produced the polyester with the highest Mn, while the Cl-substituted TPT derivatives are least active and efficient.

Ring-Opening Polymerization of Cyclic Amides (Lactams)
Saverio Russo,Elena Casazza +1 more
TL;DR: In this paper, the ring-opening polymerization of lactams is extensively reviewed, covering all aspects related to their polymerizability, in terms of both thermodynamic feasibility and kinetic likeliness, with greater attention to the many different aspects of the anionic polymerization.
