A maximum concentration of 82.4% for leave-on products and 20% for rinse off is listed for polybutene (this lower rinse-off level is likely due to it being very difficult to rinse off). Its vegan, stable, crystal clear, and doesnt smell like anything. It is characterized by low moisture absorption, excellent electrical properties, and good chemical resistance, mechanical strength, and heat resistance. The large non-polar surface area created by these long carbon chains and ease of mixing being a liquid give polybutene its sought after adhesive properties. The relative density (d415) was 0.8~0.9. 1,3-Butadiene is homopolymerized by radical or anionic chain polymerization to yield polybutadiene (BR) or copolymerized Localized stress whitening of the material generally accompanies and precedes decomposition of the polymer. Polybutene is prepared from a mixture of butene isomers, which share the same molecular formula (C4H8) but vary in the connectivity of the four carbon atoms and the location of a single carbon-carbon double bond. Connect Chemicals does market Poly alpha olefins as a product group under the brand name SinoSyn. It improves the thermal stability and the viscosity of the adhesive.[10].
