Determination of fracture toughness of propylene polymers at different operating temperatures
(Pergamon-elsevier Science Ltd, 2014-05-17)
The influence of the temperature on the fracture parameters of three types of polypropylenes under static loading conditions has been analyzed. Single-phase polypropylene homopolymer and random ethylene?propylene copolymer ...
Flexibility of the triblock copolymers modulating their penetration and expulsion mechanism in Langmuir monolayers of dihexadecyl phosphoric acid
(Elsevier Science BvAmsterdamHolanda, 2001)
Co- and terpolymerization of ethylene, propylene, and higher α-olefins with high propylene contents using metallocene catalysts
(John Wiley & Sons Inc, 2001-04)
The copolymerization of propylene/ethylene and terpolymerization of propylene/ethylene/α‐olefins using long‐chain α‐olefins such as 1‐octene and 1‐decene have been carried out using EtInd2ZrCl2//methylaluminoxane. High ...
Phase equilibrium and insulin partitioning in aqueous two-phase systems containing block copolymers and potassium phosphate
(Elsevier Science BvAmsterdamHolanda, 2004)
Subtle structural aspects of propylene-based copolymers as revealed by raman spectroscopy
(Soc Applied Spectroscopy, 2015-01)
Raman spectroscopy is used to elucidate fine details of the rather complex microstructure of ethylene-propylene copolymers (EPCs). This paper is focused on a series of commercial EPCs (Versify by Dow) with well-characterized ...
Morphological raman analysis of short chain branched ethylene and propylene metallocenic copolymers
(Elsevier, 2018-05)
Spectroscopic features in the Raman spectra of semicrystalline polyolefins that characterize different phase morphologies are reported. With growing incorporation of different 1-olefins, changes in the spectra due to ...
Effect of additives on the cloud points of aqueous solutions of ethylene oxide-propylene oxide-ethylene oxide block copolymers
