Propene polymer

Polymer molecular properties. Making a polymer of high quality is much more complicated than making butanal, for example, because the material properties of a polymer depend heavily on a number of molecular properties. For example, 1% of mistakes in a propene polymer chain can spoil the properties of a polymer completely (crystallinity for instance), while 10% of a by-product in a butanal synthesis can be removed easily by distillation. PVC contains only 0.1% defects as allylic and tertiary chlorides and this necessitates the use of a large package of stabilisers ... [Pg.192]

Ewen was the first to report the synthesis of stereoregular propene polymers with soluble Group 4 metal complexes and alumoxane as the co-catalyst [13], He found that Cp2TiPh2 with alumoxane and propene gives isotactic polypropene. This catalyst does not contain an asymmetric site that would be able to control the stereoregularity. A stereo-block-polymer is obtained, see Figure 10.6. Formation of this sequence of regular blocks is taken as a proof for the chain-end control mechanism. [Pg.198]

Organic sulphonic acids can be used instead of sulphuric acid. For example, phenol and a propene polymer having 9-24 C atoms react in the presence of 4-methylbenzenesulphonic acid monohydrate at 80-150°C to produce an 81.7% yield of 4-nonylphenol. 4-Dodecylphenol is obtained similarly (ref.11). [Pg.363]

Mechanism Analysis of the lower boiling hydrocarbon fraction from the liquid propene polymer indicates the presence of 2-methyl-l-pentene, 2-methyl-2-pentene, 4-methyl-1-pentene, and cis- and trans-4 methyl-2-pentene. These reaction products are those anticipated for a typical acid catal)rzed polymerization of propene as outlined below. [Pg.77]
