| titleOfInvention | PROCESS FOR MANUFACTURING POLYESTER THERMODURCAL FOAMS WITH PRE-IMPROVEMENT STEP |
| abstract | Method for manufacturing a thermoset polyester foam, comprising the following successive steps:n (a) heating an essentially anhydrous pre-oligomerization composition containingn - a polyol component comprising at least 30% by weight of hydrogenated sugar,n a polyacid component comprising a porogenic polyacid, preferably citric acid, andn - a catalyst,n at a temperature between 100 ° C and less than 160 ° C for a time between 10 and 60 minutes, preferably between 15 and 40 minutes, with mechanical stirring, so as to react the polyol component with the polyacid component and at form a composition of oligomeric esters,n (b) incorporation of a surfactant composition into the composition of oligomeric esters, so as to obtain an expandable thermosetting composition,n (c) introduction of the thermosetting expandable composition obtained in a mold or application of the thermosetting expandable composition on a support,n (d) heating the thermosetting expandable composition to a temperature at least equal to 160 ° C so as to form a thermoset polyester foam. |
