POLYESTER RESIN HAVING EXCELLENT HIGH WEATHER RESISTANCE AND PROCESS FOR PREPARING THE SAME

摘要

The present invention uses 0.1 to 35% by weight of the raw material for the total solids, the number average molecular weight is 1,000 to 25,000, characterized in that the average functional group is adjusted to the range of 1.5 to 2.5 to prepare a high weather resistance polyester resin And high weatherability polyester resins produced by the process.
