Mechanical Dispersions and Transition Phenomena in Semicrystalline Polymers

摘要: The existing data of mechanical dispersions in seven semicrystalline polymers (polyethylene, polypropylene, polyethylene terephthalate, polytrifluoromonochioro ethylene, polyamide, polyurethane and polytetra-fluoroethylene) are compiled the frequency dependence loss peak temperature (“transition map”) is illustrated. primary secondary occurring amorphous regions identified on basis these results. correspondence to dielectric ones, transition temperatures found dilatometric measurements change NMR line width with discussed for polymers.
