摘要：The present invention relates to multifunctional macromers, to a method forthe manufacture thereof and to their use in unsaturated polyester resins as additives toimprove mechanical properties of preparations manufactured thereof. The process forthe manufacture of multifunctional macromers comprises the following steps: a) reactinga polycarboxylic acid with 2 to 4 carboxylic groups, preferably 3 to 4 carboxylic groups,with glycidyl (meth)acrylate or allyl glycidyl ether, the amount of glycidyl (meth)acrylateor allyl glycidyl ether being at least one mol of glycidyl (meth)acrylate or allyl glycidylether per free carboxylic group of formed macromer, and b) reacting the product fromstep a) with an unsaturated, aromatic or aliphatic anhydride in an amount sufficient toesterify part or all of the free hydroxyl groups of the product from step a).
