Thermodynamic properties of polyolefin solutions at high temperature: 1. Lower critical solubility temperatures of polyethylene, polypropylene and ethylene-propylene copolymers in hydrocarbon solvents
Gérard Charlet,Geneviève Delmas +1 more
TL;DR: Lower critical solubility temperatures (LCST) of linear polyethylene (PE), isotactic polypropylene (PP), and of five random EP copolymers of different composition have been measured in (i) five linear alkanes (n-C5 to n-C9); (ii) sixteen branched alkanes and (iii) four cycloalkanes as discussed by the authors.

Gérard Charlet,Geneviève Delmas +1 more
TL;DR: In this article, the structure of poly(4-methylpentene-1) (P4MP1) is reported to have been obtained in semi-dilute solutions in linear and branched alkanes.

Effect of solvent on the polymorphism of poly(4-methylpentene-1): 1. Solution-grown single crystals
TL;DR: In this paper, the morphology and structure of poly 4-methylpentene-1 single crystals grown in a variety of solvent systems is studied by electron microscopy, electron and X-ray diffraction.

“Modification V” of poly 4-methylpentene-1 from cyclopentane solutions and gels
Gérard Charlet,Geneviève Delmas +1 more
TL;DR: In this article, a new crystalline structure of poly 4-methylpentene-1 (P4MP1), modiification named modification V, was obtained from cyclopentane solutions and gels, for polymer volume fractions between 0.01 and 0.10.

Thermodynamic properties of polyolefin solutions at high temperature: 2. Lower critical solubility temperatures for polybutene-1, polypentene-1 and poly(4-methylpentene-1) in hydrocarbon solvents and determination of the polymer-solvent interaction parameter for PB1 and one ethylene-propylene copolymer
TL;DR: In this article, the effect of CMO and solvent steric hindrance on the critical solubility temperature (LCST) of 3 polyolefins, polybutene (PB), polypentene-1 (PP), poly(4-methylpentene)-1 (P4MP1), and poly(1)-poly(2)-polyethylene (PE) was investigated.
