Method for making fire-retarded glass-filled polycarbonate and related compositions

when Lynn content oxygen acid was added to the glass filling polycarbonate composition this time, the unexpected knowledge that the resistance-to-flame performance was markedly alike, and was improved was acquired. Then, the present invention offers the production method of the fire-resistant glass filling polycarbonate resin which includes adding the Lynn content oxygen acid of the amount of effective resistances to flame in resin. Suitably, the 溶融 intensity of polycarbonate improves by addition of a drip inhibitor, and performance improves further by addition of one or more kinds of fire retardant. Use of this composite gives the outstanding resistance-to-flame performance.
