摘要:
A select polyether polyol is used in preparing flexible polyurethane foam having desirable physical properties. The select polyether polyol is an oxypropylated, oxyethylated triol containing an effectively dispersed finely divided solid particulate material. The resulting foam is of utility in various applications, such as cushioning.
摘要:
Polyol compositions containing effectively dispersed particulate material featuring critical dispersion characteristics are used to stabilize foam reaction in high resilience polyurethane foam.
摘要:
Disclosed is a process for preparing polyurethane which comprises including an azo or peroxy di-ester polyol and an ethylenically unsaturated monomer in a polyurethane reaction formulation to effect simultaneous graft copolymerization and polyurethane polymerization. Novel polyurethane compositions are produced.
摘要:
An improvement is disclosed in the preparation of high resilience polyurethane foam. The improvement resides in the use of a select reaction mixture which includes a polyol containing an effectively dispersed finely divided solid particulate material and 1,4-cyclohexanedimethanol as a cross-linking agent to stabilize the reaction mixture.
