Adamantane copolymers

[摘要] ENGLISH ABSTRACT:This study concerns the incorporation of adamantane containing monomers3-(1-adamantyl)-1-propene and 1-(1-adamantyl)-4-vinylbenzene into ethene,propene and higher a-olefins using different catalytic systems. The effect of theincorporation of the adamantane monomer on the physical and thermalproperties of the polymers was investigated. A thorough study on thebackground of adamantane in general, as well as polymerization reactionsinvolving the above-mentioned monomers and a-olefins was done.3-(1-Adamantyl)-1-propene as well as 1,.(1-adamantyl)-4-vinylbenzene wassucessfully synthesized. The homo polymers of each monomer were made. Theabove-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 influenceof the incorporation of the adamantane group on the physical and chemicalproperties of the polymers. A series of 3-phenyl-1-propene copolymers withhigher a-olefins were synthesized to compare the influence of the phenylgroup to the adamantyl group on the relevant properties of the polymers.
