Abstract:
A method for making a composition comprising a thermolyzable aqueous emulsion of a polymer substantially free of non-volatilizable substances, the method comprising:(a) preparing an aqueous emulsion of a polymer selected from the group consisting of (i) acrylics having units of formula: â€”CH2â€”CR1(CO2R2)â€”, wherein R1and R2are any radical of formula CnH2n+1 and wherein n is an integer from 0 to 10, (ii) polyhydroxyalkanoates, and mixtures thereof, wherein the emulsion contains non-volatilizable substances; and(b) removing substantially all of the non-volatilizable substances from the formed emulsion, thereby reducing levels of residue present following thermolytic removal of the polymer composition.
