Dimethyl propane

It has been observedt that poly(1,1-dimethyl propane) is the product when 3-methylbutene-l is polymerized with AICI3 in ethyl chloride at -130°C. Write structural formulas for the expected repeat units and those observed and propose an explanation. [Pg.413]

Triathyl-siliciumhydrid reduziert Halogen-alkane bei Aluminiumchlorid-Katalyse nach einem polaren Mechanismus zu Kohlenwasserstoffen. So erhalt man z. B. aus 1-Chlor-hexan 57% d.Th. Hexan, aus l-Chlor-2,2-dimethyl-propan unter Umlagerung 36% d.Th. 2-Methyl-butan bzw. aus 4-Chlor-2,2-dimethyl-butan 50% d.Th. 2,3-Dime-thyl-butans. [Pg.391]

Sanders et al. (1999) attempted to lower the melting points of aromatic polyanhydrides by substituting branched alkyl groups in place of the linear alkyls of P(CPP-SA). They synthesized poly[l,2-bis(/ -carboxyphenoxy)-propane-co-sebacic acid] (P(1,2-CPP-SA)), poly[l,3-bis(/ -carboxyphenoxy)-2-methyl propane-co-sebacic anhydride] (P(CPMP-SA)), and poly[l,3-bis (/ -carboxyphenoxy)-2,2-dimethyl propane-co-sebacic anhydride] (P(CPDP SA)), all of which had melting points below 165°C.

Radicals are referred to as hydrocarbon "backbones". As an example, isobutane is more properly named methyl propane. Another isomer with a different proper name is isopentane, more properly called methyl butane. Neopentane is also named 2,2-dimethyl propane. [Pg.161]
