Abstract
The present invention is directed to a thermosettable vinul ester resinous composition and low profile additive. The improvement comprises the low profile additive comprising a non-gelling, saturated polyester formed from dibasic acid and an ethylene oxide/propylene oxide polyether polyol having an EO/PO molar ratio ranging from about 0.1 to 0.9. The polyester has an acid value of greater than about 10 and preferably has a molecular weight of greater than about 6,000. The EO/PO polyether polyol can be built on a combination of diol, triol or other compound with active hydrogen groups, so long as the LPA product does not gel.
