Title
(EN) METHOD FOR PRODUCING SOFT POLYURETHANE FOAM BASED ON POLYESTER POLYOLS
Abstract
(EN)

The present invention relates to a process for the production of flexible polyurethane foams, wherein there is used as starting material a polyester polyol component which is composed of at least two dicarboxylic acids.
