Storage-stable two-component polyurethane or polyisocyanurate spray foam compositions are disclosed, said compositions comprising: (a) an A-side component comprising one or more polyisocyanate and one or more blowing agent; and (b) a B-side component comprising one or more polyol and one or more blowing agent comprising pressurized gaseous carbon dioxide and one or more liquid blowing agent; wherein both the A-side component and the B-side component, separately, generate less than 300 ppm of fluoride ion after one week of aging at 50° C.

Two-component polyurethane or polyisocyanurate low pressure spray foam composition containing a gaseous blowing agent comprising pressurized carbon dioxide

A faced polyisocyanurate foam board comprising a halogen-free foam made from a halogen-free foam formulation comprising isocyanate, polyol, and phosphorus-containing flame retardant, and 1.06 to 1.66 kg/m3 (30 to 47 g/ft) of glass fiber distributed in the foam throughout the thickness of the board; wherein the polyisocyanurate foam board has a trimer content of 11 to 19.5 weight percent, at least 0.1 weight percent phosphorous, and as measured by ASTM E84, a Flame Spread Index of 0 to 25 and a maximum Smoke Development Index of 450 or less.

Class a fire-retardant polyisocyanurate foam boards and process for making

The invention relates to oligomerization of olefins, such as ethylene, to higher olefins, such as a mixture of 1-hexene and 1-octene, using a catalyst system that comprises a) a source of chromium b) one or more activators and c) a phosphacycle-containing ligating compound. Additionally, the invention relates to a phosphacycle-containing ligating compound and a process for making said compound.

Chromium complex and catalyst therefrom

Storage-stable two-component polyurethane or polyisocyanurate spray foam compositions are disclosed, said compositions comprising: (a) an A-side component comprising one or more polyisocyanate and one or more catalyst; and (b) a B-side component comprising one or more polyol; and further comprising one or more hydrohaloolefin blowing agent in either the A-side component or the B-side component, or in both; wherein both the A-side component and the B-side component, separately, generate less than 600 ppm of fluoride ion after two weeks of aging at 50&#xb0; C.

Two-component polyurethane or polyisocyanurate spray foam composition containing a hydrohaloolefin blowing agent

Storage-stable two-component polyurethane or polyisocyanurate spray foam compositions are disclosed, said compositions comprising: (a) an A-side component comprising one or more polyisocyanate and one or more blowing agent; and (b) a B-side component comprising one or more polyol and one or more blowing agent comprising pressurized gaseous carbon dioxide and one or more liquid blowing agent; wherein both the A-side component and the B-side component, separately, generate less than 300 ppm of fluoride ion after one week of aging at 50&#xb0; C.

Process for oligomerization

Provided is a composition comprising one or more phenanthroquinazoline-core compounds having structure (I) wherein each of Rand Ris independently a substituted or unsubstituted phenyl group.
