Abstract
A fluid, filled, curable composition comprising an organic liquid which is polymerizable to form a solid polymer without the formation of any elimination products and from 20 to 70% by volume of alumina trihydrate filler characterized in that filler has a median particle size of between 5 and 30 microns, and preferably between 6 and 20 microns, and has an average aspect ratio of less than 2,5:1, preferably less than 2.0:1, and desirably less than 1.8:1. The composition when cured provides shaped articles having improved mechanical properties and when used as a dispersion of low viscosity reduces the tendency for the composition to show color variations through the thickness of the sheet as exhibited using alumina trihydrate fillers of high aspect ratio.
