High-temperature creep behaviors of polybutene-1 with different chain microstructure and molecular weight

open access: goldPolymer Testing, 2023
The creep resistance of polymer determines the dimensional stability of product under stress. The isotactic polybutene-1 (iPB) with outstanding high-temperature creep resistance and stress-crack resistance is applied widely in the field of hot-water ...

The Stability of Viscosity of Polybutenes and Polybutene-Mineral Oil Mixtures

open access: bronzeJournal of the Society of Materials Science, Japan, 1973
In order to obtain the data of the stability of high viscosity standard oils, the variation of viscosity with age was measured by means of a caoillary master viscometer for nolybutenes having viscosities of 55, 340, and 1010 poises at 25°C, and for polybutene-mineral oil mixtures having viscosities of 20, 100, and 540 poises at 25°C.The results ...
