Co-crystallization in polyolefin blends studied by various crystallization analysis techniques

Sweed, Muhamed (Stellenbosch : University of Stellenbosch, 2006-03)

Co-crystallization is the phenomenon by which chains of different crystallizabilities crystallize at the same temperature. Co-crystallization is frequently observed in the blends of different types of polyethylene. It ...
A comparative analysis of the chemical composition of linear low density polyethylene polymers synthesised with 1- hexene comonomer under different catalytic conditions

Naidoo, Preloshni (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: A comparative study of the chemical composition of linear low density polyethylene polymers, synthesised with 1 - hexene as comonomer was conducted. Catalyst trials were conducted on the linear low density ...
The fractionation and characterisation of propylene-ethylene random copolymers

Harding, Gareth (Stellenbosch : University of Stellenbosch, 2005-12)

This study involves the fractionation and characterisation of three propyleneethylene random copolymers. The fractionation technique used in the study was temperature rising elution fractionation (TREF). The TREF fractions ...
