The unsaturated aliphatic hydrocarbons, such as 4-METHYL-1-PENTENE, are generally much more reactive than the alkanes. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen. 2,3-Dimethyl-1-butene was used to investigate the mechanism of the sulfur vulcanization of rubber. Packaging 5 g in glass bottle Safety & Documentation. Safety Information. Symbol GHS02, GHS08. Signal word Danger. Hazard statements H225-H304. Precautionary 01/06/1993 · The polymorphic behaviour of isotactic poly(4-methyl-1-pentene) is discussed on the basis of conformational energy calculations. A preliminary model of packing of form III is presented. Chains having helical conformations with 4/1 symmetry are packed in a tetragonal body-centered unit cell with axesa = 19.38 Å,c = 6.98 Å. Il comportamento polimorfo del poli(4 … 2-METHYL-1-PENTENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions. Copolymers of 4-methylpentene-1 and styrene were prepared (TiCl3-AliBu3, 70°) and their structure investigated. Monomer reactivity ratios calculated f…
