Thesis (PhD)--Stellenbosch University, 2001. / ENGLISH ABSTRACT: This study concerns the incorporation of adamantane containing monomers
3-(1-adamantyl)-1-propene and 1-(1-adamantyl)-4-vinylbenzene into ethene,
propene and higher a-olefins using different catalytic systems. The effect of the
incorporation of the adamantane monomer on the physical and thermal
properties of the polymers was investigated. A thorough study on the
background of adamantane in general, as well as polymerization reactions
involving the above-mentioned monomers and a-olefins was done.
3-(1-Adamantyl)-1-propene as well as 1,.(1-adamantyl)-4-vinylbenzene was
sucessfully synthesized. The homo polymers of each monomer were made. The
above-mentioned monomers were also polymerized:
• . 3-( 1-adamantyl)-1-propene with ethene, propene and higher a-olefins,
• 1-(1-adamantyl)-4-vinylbenzene with ethene and styrene.
The copolymers of 3-(1-adamantyl)-propene as well as 1-(1-adamantyl)-
4-vinylbenzene were characterized as far as possible to show the influence
of the incorporation of the adamantane group on the physical and chemical
properties of the polymers. A series of 3-phenyl-1-propene copolymers with
higher a-olefins were synthesized to compare the influence of the phenyl
group to the adamantyl group on the relevant properties of the polymers. / AFRIKAANSE OPSOMMING: Hierdie studie behels die inkorporasie van adamantaan-bevattende monomere,
3-( 1-adamantiel)-1-propeen en 1-(1-adamantiel)-4-vinielbenseen in eteen,
propeen en hoër a-olefiene met behulp van verskillende katalitiese sisteme. Die
effek wat die inkorporasie van die adamantaan monomeer op die fisiese en
chemiese eienskappe van die polimere het, is ondersoek. 'n Deeglike studie van
die agtergrond van adamantaan in die geheel, sowel as die polimerisasie
reaksies van die bogenoemde monomere met a-olefiene, is gedoen.
3-( 1-Adamantiel)-1-propeen sowel as 1-(1-adamantiel)-4-vinielbenseen is
suksesvol berei. Die homopolimere van bogenoemde monomere is
gesintetiseer. Bogenoemde monomere is gepolimeriseer:
• 3-(1-adamantiel)-1-propeen met eteen, propeen en hoër a-olefiene,
• 1-(1-adamantiel)-4-vinielbenseen met eteen en stireen.
Die kopolimere van 3-(1-adamantiel)-1-propeen en 1-(1-adamantiel)-
4-vinielbenseen is sover moontlik gekarakteriseer om die invloed van die
adamantaan groep op die fisiese en chemiese eienskappe van die polimeer
te toon. 'n Reeks kopolimere van 3-(1-feniel)-1-propeen met hoër a-olefiene
is gesintetiseer om die verwantskap tussen die invloed van die fenielgroep
en die adamantielgroep op die relevante eienskappe van die polimere te
toon.
