Your access to the NCBI website at www.ncbi.nlm.nih.gov has been The formation of poly (ethene) from ethene is an example of addition polymerisation. Being the name for a family of related molecules, the exact physical properties of polybutene such as density, viscosity, average molecular weight and refractive index varies from each specific polybutene product. [19], There is evidence to suggest that the presence of chlorine and chloramine compounds in municipal water (often deliberately added to retard bacterial growth) will cause deterioration of the internal chemical structure of polybutylene piping and the associated acetal fittings. . Liquid polybutene is also usedas a thinnerin the manufacture of many hot-melt adhesives (otherwise known as hot glue) at a specific melting point. Polybutene is safe to use, because it is non-toxic. Butanediamide, N,N-bis3-(9Z)-9-octadecenylaminopropyl-, polybutenyl derivs. [11] The use of PB-1 foam as thermal insulation is of great advantage for district heating pipes, since the number of materials in the sandwich structure is reduced to one, facilitating its recycling.[12].
