Abstract
The silanized (meth)acrylate (I) is manufactured by reacting the anhydride (II) with a silanized compound (III). This process gives a crude mixture containing compound (IV) in addition to compound (I), after which the said mixture may be freed of the lightest compounds by distillation or may be subjected to a distillation to obtain the pure compound (I). 1 R=H or Me; R1, R2, R3=linear or branched C1-C10 alkyl, aryl or aralkyl, these radicals possibly being substituted and possibly containing hetero atoms; R4=H or a radical falling within the definition given above for R1, R2 and R3.
Claims12
Process for manufacturing a silanized (meth)acrylate of formula:
- 14
- in which:
- R represents hydrogen or methyl;
- R1, R2 and R3 each independently represent a linear or branched C1-C10 alkyl radical, an aryl radical or an aralkyl radical, these radicals possibly being substituted and possibly containing hetero atoms characterized in that the anhydride of formula (II):
- 15
- in which R is as defined above,
- is reacted with a silanized compound of formula (III)
- 16
- in which:
- R1, R2 and R3 are as defined above;
- and
- R4 represents hydrogen or a radical falling within the definition given above for R1, R2 and R3.
