  • Preparation of in situ-reticulated flexible polyurethane foams
    Patent number: 6638986
    Abstract: Reticulated flexible polyurethane foams are prepared by reacting organic and/or modified organic polyisocyanates (a) with a polyetherol mixture (b) and, if required, further compounds (c) having hydrogen atoms reactive toward isocyanates, in the presence of water and/or other blowing agents (d), catalysts (e) and further assistants and additives (f), by a process in which the polyetherol mixture (b) comprises b1) at least one difunctional or polyfunctional polyetherol having an OH number of from 20 to 150 mg KOH/g, based on propylene oxide and/or butylene oxide and ethylene oxide and having an ethylene oxide content of more than 40% by weight, based on the total amount of alkylene oxide used, (b1.

  • Preparation of low-density hydrophilic flexible polyurethane foams
    Patent number: 6586486
    Abstract: Low-density hydrophilic flexible polyurethane foams are prepared by reacting organic and/or modified organic polyisocyanates (a) with a polyetherol mixture (b) and, if required, further compounds (c) having hydrogen atoms reactive toward isocyanates, in the presence of water and/or other blowing agents (d), catalysts (e) and, if required, further assistants and additives (f), by a process in which the polyetherol mixture (b) consists of b1) at least one difunctional or polyfunctional polyetherol based on propylene oxide and/or butylene oxide and ethylene oxide, having an ethylene oxide content of more than 40% by weight, based on the total amount of alkylene oxide used, an OH number of from 20 to 120 mg KOH/g and a proportion of primary OH groups of more than 20% and b2) at least one difunctional or polyfunctional polyetherol based on propylene oxide and/or butylene oxide and, if required, ethylene oxide, the ethylene oxide content being not more than 40% by weight, and having an OH number of more than 25 m
