Abstract: A pressure-sensitive adhesive (PSA) composition and method of use across a wide operable temperature window. The PSA composition includes a triblock copolymer rubber with relatively low diblock content, an aliphatic tackifier, an aromatic tackifier, and an oil-based plasticizer. The combination of components results in the PSA having a phase-separated morphology, where the PSA includes two domains that do not mix with each other. This morphology’ results in superior performance of the PSA across a wide range of temperatures, such that separate adhesives for low temperatures and high temperatures are no longer required.

Abstract: Processes for manufacturing novolacs and resoles from lignin are disclosed. A phenol-aldehyde-lignin dispersion is formed which can then be used to make either a novolac or a resole, depending upon the catalysts used.

Abstract: A gas turbine power plant comprises a gas turbine, a power turbine, a clutch, an electrical generator and a controller. The power turbine is fluidly connected to the gas turbine without any mechanical connection. The clutch comprises an input mechanically connected to the power turbine and an output mechanically connected to the electric generator. The controller can identify that a speed of the electric generator is greater than a speed of the power turbine, determine a difference between the speed of the electric generator and the power turbine, in response to the difference being greater than a threshold, control the gas turbine to a first maximum acceleration of the power turbine, and in response to the difference being equal or less than to the threshold, control the gas turbine to a second maximum acceleration of the power turbine that is less than the first maximum acceleration.

Abstract: The invention relates to a composition that contains a binary mixture of bisphenol F and propoxylated bisphenol F. The aim of the invention is to provide aromatic polyols for preparing polyurethane-based and polyisocyanurate-based polymers, which ensure good handling from a technical point of view and good miscibility with the isocyanate component and render the end product flameproof. For this purpose, the invention devises a composition, which contains a binary mixture of ethoxylated bisphenol F and propoxylated bisphenol F in a weight ratio of 20:80 to 80:20.
