PROCEDURE FOR THE PRODUCTION OF A RESILIENT AND STABLE POLYESTER FOAM. |
| abstract |
Procedure for. the production of a resilient and stable polyester foam, essentially closed cell, with approximately 50 to 400 cells per linear cm and with a density of approximately 0.06 g/cm3; characterized in that it comprises reacting: (a) at least one polyol having at least two hydroxyl groups and an equivalent weight of at least about 1,000; (b) at least one propylene oxide-based polyhydroxy crosslinking agent having at least three hydroxyl groups and an equivalent weight of less than about 250; and (c) at least one acyl halide having at least two radicals -COX where X is a halogen atom; the co-reaction being carried out in the presence of an alkali metal carbonate. |
