<p>A process for forming a polymerizable, liquid, substantially gel-free, poly(allyl carbonate)-functional prepolymer composition comprises heating a neat composition comprising at least one poly(allyl carbonate)-functional monomer and free radical initiator having a ten-hour half-life temperature of at least 85 °C at temperatures in the range of from 5 Celsius degrees below the ten-hour half-life temperature of the free radical initiator to 150 °C, to form a reaction mixture having an increased 25 °C viscosity in the range of from 25 to 10,000 centipoises and an ethylenic double bond utilization of at least 3 percent; and over a period of less than 90 minutes cooling the reaction mixture to a temperature at least 20 Celsius degrees below the ten-hour half-life temperature of the initiator.</p> |
