Understanding of the behaviour of F-containing polymers has very recently been broadened by studies of three methacrylate polymers in which the ester group contains fluorine poly-(2-fluoroethyl methacrylate) (PFEMA), poly(2,2,2-trifluoroethyl methacrylate) (PTFEMA) and poly(hexafluoroisopropyl methacrylate) (PHFPMA). The experimental approach used is flash pyrolysis of microgram quantities of polymer at 600 °C in a helium atmosphere, followed by GC separation of volatile products and identification by MS. This produces a convenient picture of the number and relative importance of the volatile products. [Pg.1244]

The poly(p-dioxanone-co-e-caprolactone) block copolymer had an inherent viscosity of 2.18 dL/g in hexafluoroisopropyl alcohol (HFIP) at 25°C, and a melting point by hot stage microscopy of 110°C. [Pg.62]

In addition to its biodegradability and biocompatibility, PPDX is a semicrystalline poly(ester-alt-ether) with a Tg at approximately -10 ° C and Tm at around 110 ° C. PPDX has shown to be tougher than PLAs and even HDPE with a tensile strength close to 50 MPa for an ultimate elongation ranging from 500 to 600% (Figure 17). PPDX is poorly soluble expect in exotic solvents such as hexafluoroisopropyl, 1,1,2,2-tetrachloroethane, dimethyl sulfoxide, N,N-dimethyl formaldehyde, and 1,2-dichloro ethane. ... [Pg.773]
