  • POLYETHER POLYOL PROVIDING GOOD BLOW-GEL BALANCE FOR POLYURETHANE PRODUCTS MADE THEREFROM
    Publication number: 20170058077
    Abstract: The present invention discloses a tertiary amine initiator and polymeric polyol compositions made therefrom useful for making polyurethane polymers, especially polyurethane foams. Said polyurethane polymer foams demonstrate a good balance of mechanical properties, physical properties and low emissions. The tertiary amine initiator is the reaction product of a dihydroxy tertiary amine and a polyhydroxy alcohol, such as the reaction product of N-methyl ethanolamine and glycerine.
