Abstract

The functionalization of elastomers by phosphonate groups remains relatively unexplored considering the great potential these polymers would represent for applications. In this paper, thiol-functional oligophosphonates were designed and coupled by a thiol-ene reaction to a styrene-butadiene rubber (SBR). We adopted a RAFT methodology with dimethyl vinylphosphonate (DMVP) and a high-temperature thermolysable xanthate, to afford the monophosphonate DMVP-SH and P(DMVP)5-SH, a mercapto(oligophosphonate) of DPn = 5. We conducted a comparative study of the thiol-ene coupling reaction of DMVP-SH and P(DMVP)5-SH with a SBR for different degrees of functionalization. We observed that P(DMVP)5-SH was as reactive as DMVP-SH. Although only limited grafting could be achieved without alteration of the SBR structure by radical intercoupling reactions, P(DMVP)5-SH was found superior to DMVP-SH for increasing the phosphonate content of the SBR thanks to its oligophosphonate character.

Abstract

Ceramic supports from bentonite have become a hot research topic because of their low cost and abundance in many countries. This article describes the development and the characterization of a microfiltration support elaborated using an extrusion method followed by sintering at different temperatures (950, 1000, and 1100 °C). X-ray fluorescence, X-ray diffraction, Fourier transform infrared, scanning electron microscopy, transmission electron microscopy, and differential thermal analysis were used for the characterization of the raw material. The resulting support was characterized by scanning electron microscopy, mechanical and chemical resistance, and water permeability. Each tube was 150 mm in length, with an external diameter of 8 mm and an internal diameter of 5 mm.

Abstract

Dibenzyltrithiocarbonate-mediated RAFT polymer- ization of dimethyl-p-vinylbenzylphosphonate and its copoly- merization with styrene are studied in order to access well- defined statistical and block copolymers containing controlled amounts of dimethylphosphonate groups. NMR and SEC anal- ysis of the (co)polymers confirm the controlled character of the polymerizations. ABA triblock copolymers are treated with TMSiBr/MeOH in order to transform the dimethylphosphonate groups into phosphonic acids while keeping the midchain tri- thiocarbonate group and triblock nature unaffected. Alterna- tively, the combination of trithiocarbonate aminolysis with TMSiBr/MeOH treatment of the same triblock copolymers leads to phosphonic acid-functional diblock copolymer counterparts.

Abstract

RAFT/MADIX polymerisation of vinylphosphonic acid (VPA) was controlled in water with an O-ethyl xanthate transfer agent. This represents the first example of reversible deactivation radical polymerisation of a monomer bearing an unprotected phosphonic acid function. Hence, macromolecular engineering of polyphosphonates can now be envisioned by directly polymerising VPA in water.
