Thermal degradation and kinetics of poly(4-methyl-1-pentene) were investigated by nonisothermal high-resolution thermogravimetry at a variable heating rate. Thermal degradation temperatures are higher, but the maximum degradation rates are lower in nitrogen than in air. The degradation process in ni
## SYNOPSIS Sorption and volume dilation isotherms of semicrystalline poly(4-methyl-1-pentene) (PMP) were measured using COP and C3Hs as penetrants, which have sieving diameters of 3.3 and 4.3 A, respectively. On the other hand, the PMP crystal has a void width of approximately 4 A as estimated by
## SYNOPSIS The fluorinated surface layer of poly (4-methyl-1-pentene) membranes exposed to a dilute stream of fluorine gas has been characterized with X-ray photoelectron spectroscopy. The concentration and profile of reacted fluorine as a function of exposure time is determined. A computer rout
