Patent

CA 2367068

The invention describes polyesters containing (meth)acrylate end groups, of the general formula (I) CH2=CRCOO-PE-OCOCR=CH2 where R = CH3 or H, where PE = [-A-OCO-B-COO-]m-A-, [-CHR'-COO-]n- A-[-OCOCHR'-]n, in which A is an alkylidene radical having 2-20 carbon atoms or an alkoxylidene radical having 2-1000 alkoxylidene units, B is a saturated alkylidene radical having 2-10 carbon atoms, R' is H or CH3, m is 0-100, n is 0-100, with the proviso that the sum m + n is 2-200, where the polyesters containing (meth)acrylate end groups are characterised in that a) the content of short-chain di(meth)acrylates (II) CH2=CRCOO-A- OCOCR=CH2 is < 5% by weight, b) the content of hydroxyl groups is < 0.25 mol/mol of (meth)acrylate, and c) the APHA colour number is < 200.
