Compositions containing half esters of organic polyols, a process for their production and use of the compositions in the production of moulded articles.

摘要

The invention comprises a homogeneous liquid mixture of (a) a half ester of an organic polyol characterized by the following empirical formula:
<Chemistry id="chema01" num="0001"><Image id="ia01" he="11" wi="67" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein n is a number having an average value of about 1.8 to less than about 4, m is equal to the free valence of R less the average value of n, R is the hydroxyl-free residue of an organic polyol which contained from 2 to 4, inclusive, hydroxyl groups, OH, in formula (I), (b) maleic anhydride, (c) an ethylenically unsaturated monomer which forms a liquid homogeneous mixture with and is copolymerizable with the half ester and maleic anhydride, and (d) a basic compound.
