The process disclosed includes an extruder under extrusion conditions at a temperature from 50° C. to 250° C., and a polymer composition. The polymer composition includes (A) greater than or equal to 5 wt % of a silane functionalized olefin-based polymer with first melting temperature, Tm1, (B) optionally, a nonsilane functionalized polyolefin, with second melting temperature, Tm2, (C) a highly effective silanol condensation catalyst (HEC), (D) a permeability modifier, and (E) optionally, a scorch inhibitor. The process includes introducing a physical blowing agent into the polymer composition to form a foamable composition. The foamable composition is cooled to a foaming temperature from 10° C. less than to 10° C. greater than Tm1. The foamable composition from an extruder exit die to form a foam composition. The foam composition is moisture cured to form a crosslinked foam composition having a density from 0.010 g/cc to 0.200 g/cc, and a gel content from 5% to 100%.

The invention relates to the use of i) geopolymer and ii) non-brominated, phosphorus- and/or nitrogen-based flame retardants for improving the self-extinguishing properties of a composition comprising polymer. The polymer may be a vinyl aromatic polymer, and may be in a granulate or foam.

The present invention relates to sulfur-containing polyester polyols and to the preparation and use thereof.

A method of producing a polyurethane or polyisocyanurate foam is provided which involves the use of a specific combination of hydrofluoroolefin blowing agents and cell nucleators. The resulting foams have excellent long term thermal insulating performance and have reduced thickness in comparison to conventional thermal insulating boards. The rigid polyurethane and polyisocyanurate boards may be used to insulate refrigeration bodies, such as those employed in vehicles comprising refrigeration units, and cold storage containers.

The invention relates to a method for producing isocyanurates and isocyanurate-containing polyurethanes, comprising the step of reacting an isocyanate in the presence of a catalyst.
