Glass transition temperatures, specific volumes and viscosities of concentrated solutions of two diolic (functionalized) perfluoropolyoxyalkylene oligomers in various solvents are reported. It is shown that polar solvents, generally considered poor o

Viscosities and densities of two low molecular weight perfluoropolyoxyalkylene diols in 11 polar solvents are analysed. The specific volume-concentration behaviour shows the presence of an excess mixing volume common to all the solvents tested. Plots

Twelve series of linear oligomers of four different degrees of polymerization ( x n = 8.77−41.55), having a common perfluorinated random copolymeric chain as molecular body and two equal foreign end units of one of the types listed in Table 1, have

Conditions required for the molecular weight and molecular weight distribution determination of fluoropolyoxyalkylenes by gel permeation chromatography are reported and discussed. Experimental work was carried out with three series of narrow fraction

Investigations have been carried out by different methods on the rheological properties, both shear and tensile, of some unfractionated samples of low density polyethylene, the molecular characteristics and long chain branching content being known. F

The thermodynamic parameters of fusion and crystallization kinetics of cis-polyoctenamer were investigated. We adopted the cryoscopic method based on the melting point decrease in the presence of diluents, using toluene as a diluent. It was also poss

Modification 3 of isotactic polybutene-1, prepared by crystallization from a solution at room temperature, was studied by dilatometric and X-ray examinations at different temperatures. At high degrees of crystallinity, its specific volume is intermed

Melting temperature, enthalpy and entropy of a sample of highly isotactic polybutene-1 in each of the three polymorphic modifications as yet recognized, are determined by the method of the depression of the melting point in the presence of diluents.

Preliminary results of a physical study of highly isotactic poly-pentene-1 are here reported. This polymer, although crystallizable to a high degree, can be fractionated by a normal fractional precipitation technique. This is due to its capacity of g
