Catalysis of the ring‐opening reaction of L‐lactide and ε‐caprolactone to form the corresponding biodegradable polyesters is frequently performed using organometallic compounds such as tin(II) 2‐ethylhexanoate, which operates by a living, coordination insertion mechanism. For biomedical applications, non‐toxic calcium salts have been researched but these rarely approach the same efficiency. The use of heterogeneous immobilized catalysts offers an alternative approach, but competing reactions such as transesterification affect the final molecular weight and polydispersity. The formation of hybrid materials by using silica as the initiation site offers the prospect of biomaterials with novel properties. Copyright © 2009 Society of Chemical Industry

“…Polymer chains tethering onto an inorganic surface can be performed following three main routes: chemisorption of a reactive polymer end group to the surface (“grafting to”),10–13 copolymerization with grafted co‐monomer onto the inorganic surface (“grafting through”) 14–16 and the growth of polymer chains from chemically linked initiator onto the inorganic surface (“grafting from”) 17–19. With respect to the recent development in controlled/“living” radical polymerization (CRP), the “grafting from” way becomes the most powerful strategy to finely tune the dimension, functionality, composition and graft density of the polymer brushes on inorganic surfaces 20–26…”

A colored polymer/aluminium hybrid pigment was synthesized by nitroxide mediated polymerization initiated from an inorganic surface. This approach requires the preparation of a vinyl dye monomer able to copolymerize with n‐butyl acrylate (n‐BuA) and styrene (S) from the surface of aluminium flakes. The linearity of the ln([M]0/[M]t) and of the $\overline M _{\rm n}$ as a function of time and conversion constitute the criteria of control/“living” polymerization, i.e. linearity of respectively ln([M]0/[M]t) = f(t) and the $\overline M _{\rm n}$ = f(conversion) plots. Kinetic measurements reveal an upward deviation from the linearity for n‐BuA polymerization for very high conversion. The introduction of S monomer restores the control of the polymerization. Both the length of the grafted chains and the dye/styrene molar ratio influence the color of the hybrid material.magnified image
