dc.description.abstractENGLISH ABSTRACT: In this study, the feasibility of the non-conjugated 1,5-hexadiene as monomer in metallocene catalised cyclopolymerizations was considered. Homopolymers and copolymers with ethylene, propylene, 1-pentene, 1-hexene and 2-methyl-1,5- hexadiene as comonomers were synthesised in the presence of Cp2ZrCh and rac-Et(lnd)2Zrh. The microstructure (stereoregularity and cyclisation) and number-average molecular weight were determined from NMR analysis. Crystalline oligomers with functional (eg -OH) and vinylidene end groups were obtained.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: Die studie behels die ondersoek rakende die gebruik van ongekonjugeerde 1,5- heksadieen as monomeer in metalloseengekataliseerde polimerisasies. Homopolimere, sowel as kopolimere van etlieen, propileen, 1-penteen, 1- hekseen en 2-metiel-1,5-heksadieen, is in die teenwoordigheid van Cp2ZrChen rac-Et(lnd)2ZrCI2 gepolimeriseer. Die mikrostruktuur (stereochemie en siklisering) en die getal-gemiddelde molekulêre gewig van die gesintetiseerde polimere is met behulp van KMR spektroskopie ondersoek. Die studie het getoon dat kristallyne oligomere met funksionele (bv -OH) en vinilideen endgroepe gesintetiseer is.af_ZA
