In a semicrystalline polymer chain, if n is the total number of backbone units and a is the number of nonlattice backbone units, then the per cent crystallinity is (n – a)/n. By an empirical approach it is found that if a is set equal to ca. 40 for

The steady-state and dynamic melt rheology for a series of poly(1-olefins) has been investigated. The series includes poly(1-butene), poly(1-hexene), poly(1-heptene), poly(1-octene), Poly(1-undecene), poly(1-tridecene), poly(1-hexadecene), and poly(1

Poly(1-olefin)s from poly(1-butene) up to poly(1-octadecene) have been characterized. The melting point was measured by Differential Scanning Calorimetry (DSC-1B) and dilatometry, the specific volume and volume expansion coefficient by dilatometry, a

The effects of shock cooling and swelling with carbon tetrachloride on the dynamic mechanical spectrum of high density polyethylene have been studied with a torsional pendulum. The resulting spectra have a well-defined loss peak at −65°C which is
