The process also has at least one foam stabilizer and optionally one or more chemical or physical blowing agents. The employed recycled polyol has a total concentration of antioxidants of formula 3a and/or formula 1d of 0.001% to 10% by weight, preferably 0.002% to 8% by weight, further preferably 0.005% to 7.5% by weight, and particularly preferably 0.01% to 5% by weight, based on the total recycled polyol.

Abstract: Polymer polyols (“PMPOs”), processes for their production, and the use of such PMPOs, particularly in the production of flexible polyurethane foams. The PMPOs are produced using an ethylenically unsaturated composition that includes a crosslinker that results in crosslinks in the PMPO polymer particles that may decompose when exposed to flame temperatures. The PMPOs is capable of providing a flexible polyurethane foam that may exhibit combustibility resistance properties.

Abstract: Modified lignin products, processes for making them, and their use to produce rigid polyurethane or polyisocyanurate foams are disclosed. The processes comprise heating a lignin source with a nitrogen source and a starved concentration of a C1-C5 aldehyde to give a reaction mixture comprising a Mannich condensation product, neutralizing the reaction mixture, and isolating the modified lignin product. The process is performed at a mass ratio of lignin source to nitrogen source within the range of 1:1 to 1:5 and at a molar ratio of nitrogen source to C1-C5 aldehyde within the range of 3.5:1 to 1:1. Polyol blends and performance additives that contain the modified lignin products are described. Rigid foams that process well and incorporate up to 60 wt. %, based on the amount of polyol component, of the modified lignin contribute to excellent flame retardancy and low-temperature R-value performance.
