“…18 This behavior is the result of a degradative chain transfer; the weakness of the allyl C-H bond arises from the high resonance stability of the allylic radical, which is too stable to reinitiate polymerization and undergoes termination by reaction with propagating radicals. 19 Radical polymerizations of dioxaphosphorinane monomers were then carried out in the presence of dimethylhydrogenophosphonate HP(O)(OMe) 2 as chain transfer agent (CTA) (Scheme 5).…”

International audienceWe report here the investigation of new flame retardant compounds for textiles, obtained by radical polymerization of allyloxydioxaphosphorinanes. These monomers were first synthesized by a transesterification reaction. A deep NMR study of such compounds revealed the existence of diastereoisomers Z and E. Radical polymerizations of allyloxydioxaphosphorinanes in the presence of a chain transfer agent, i.e. dimethylhydrogenophosphonate, led to oligomers of rather low molecular weights and especially adducts with DP 1 and 2. It was demonstrated that radical polymerization of allyloxydioxaphosphorinanes with P-R (R being alkyl or aryl) does afford only linear oligomers instead of hyperbranched polymers when R is hydrogen. The thermogravimetric analyses of the oligomers showed a good thermal stability and a high content of char residue (more than 16 wt%). The flame retardant properties were also evaluated by microcalorimeter tests and revealed an efficient behavior especially in the condensed phase, comparatively to Antiblaze 19, the flame retardant commercial product for polyester textile

“…If functional initiators and chain transfer reagents are selected appropriately, the a,v-difunctional polymers can be directly prepared from free radical polymerization of vinyl monomers without the following chemical modification. One example is the preparation of a,v-dihydroxyl polymers including polystyrene (PSt), poly(vinyl acetate), poly(methyl methacrylate) (PMMA) and poly(methyl acrylate) (PMA) [15]. They were obtained by free radical polymerization with N,N 0 -azobiscyanopropanol as initiator and allyl alcohol as chain transfer agent.…”

“…[17][18][19] Cho et al have synthesized diblock copolymer consisting of PNIPAM as hydrophilic block and poly(c-benzyl L-glutamate) as hydrophobic block. 20,21 The core-shell nanoparticles were obtained by the diafiltration method. The size of the nanoparticles was unchanged between 25 and 40 C. While it was found that the size distribution of the nanoparticles was very large.…”

The addition of mixture of polystyrene-b-poly(N-isopropylacrylamide) (PS-b-PNIPAM) and polystyrene homopolymer (h-PS) in tetrahydrofuran dropwise into water leads to nanoparticles with a PS core and a thermally sensitive PNIPAM shell. The effects of the ratio of the homopolymer to copolymer and temperature on the formation and stabilization of the dispersion were investigated by using a combination of static and dynamic laser light scattering. PNIPAM shell continuously collapses as temperature increases in the range 20-40 C. Such formed particles are stable even at temperatures much higher than lower critical solution temperature (LCST $ 32 C) of PNIPAM. Our results reveal that the area occu-pied per hydrophilic PNIPAM chain on the hydrophobic PS core remains nearly a constant regardless of the amount of h-PS in the polymer mixture. This clearly indicates that the surface area occupied per hydrophilic group is a critical parameter for stabilizing particles dispersed in water. V C 2010 Wiley Periodicals, Inc.
