Abstract
The present invention relates to a composition based on isocyanate(s), advantageously not completely masked. This composition is defined in that it comprises a compound containing an anionic functional group and a polyethylene glycol chain fragment of at least 5, advantageously of at least 7 ethyleneoxy units. Application to organic synthesis.
Claims27
Composition based on isocyanate(s), advantageously not completely masked, characterized in that it comprises at least one compound containing an anionic functional group and advantageously a polyethylene glycol chain fragment of at least one, preferably at least 5 ethyleneoxy units.
Process for emulsifying isocyanate 13, characterized in that [lacuna] comprises the following step:
- addition of the isocyanate to the mixture polyol+water.
Process for the preparation of a coating 18, characterized in that it comprises the application of a layer of between 10 to 150 micrometres, advantageously 20 to 80 dry, that is between 30 and 40 to micrometres, wet 60 and 150 micrometres. [sic]
Compound of formula,
- 16
- Where E is an element of column VA [lacuna] the Periodic Classification of the Elements [(supplement to the Bulletin de la Société Chimique de France January 1966 No. 1) advantageously phosphorus]. And therefore especially of the type:
- 17
- Where Iso is the residue (of a poly)isocyanate (after removal of one isocyanate functional group)
- where R10 is a negative charge or a hydrocarbon residue (that is to say containing hydrogen and carbon atoms) whose point of attachment [that is to say the atom carrying the open bond] is a carbon.
- where R11 is chosen from:
- a negative charge;
- a group of formula II:
- 18
- in which R′10 is chosen from hydrocarbon residues (similar to or different from R10) and a negative charge whose point of attachment [that is to say the atom carrying the open bond] is a carbon
- in which the R′11(s) is(are) chosen from hydrocarbon residues whose point of attachment [that is to say the atom carrying the open bond] is a carbon (which are similar to or different from R10 and R′11) and a negative charge.
