along the backbone of the unsaturated polyester prepolymer and wherein the unsaturated polyester prepolymer has terminal acid
and/or hydroxyl functional groups,

(b) subjecting the unsaturated polyester prepolymer to free radical polymerization via the points of unsaturation along the
unsaturated polyester prepolymer backbone to form the ungelled crosslinkable polyester resin that has a weight average molecular
weight of 10,000 to 4,000,000 and that has a higher weight average molecular weight than the unsaturated polyester prepolymer
such that the weight average molecular weight ratio of the ungelled crosslinkable polyester resin to the unsaturated polyester
prepolymer is at least 1.2 and the hydroxyl value and the acid value of the ungelled crosslinkable polyester resin is in the
same range as those of the prepolymer; wherein the hydroxyl value of the unsaturated polyester prepolymer ranges from 2 to
500 mg KOH/gm and/or the acid value of the unsaturated polyester prepolymer ranges from 1 to 400 mg KOH/gm.

AEROSPACE TRANSPARENCY HAVING MOISTURE SENSORS

PPG Industries Ohio, Inc....

1. A transparency comprising:a plurality of sheets joined together to provide a laminated window having a vision area, the window having a moisture seal on peripheral and marginal edge portions of the sheets;
a moisture sensor positioned between the sheets and/or between the sheets and the moisture seal, wherein the moisture sensor comprises an electrolyte member comprising at least one of an extruded polymer sleeve and an extruded polymer layer loaded with an electrolyte material, the electrolyte layer being between a first electrode and a second electrode, and wherein the electrolyte material is in ionic contact with the first and second electrodes and maintains the first and the second electrodes spaced from one another and out of surface contact with one another; and
sensor electronics operatively connected to the electrodes of the moisture sensor to measure a potential between the first electrode and the second electrode and/or to measure a current through the sensor generated by a reaction of the electrolyte material and moisture absorbed by the electrolyte material to determine an amount of moisture absorbed by the electrolyte member, wherein the potential between the first and the second electrode and/or the current through the sensor measures the amount of moisture within the laminated windshield in an area of the moisture sensor.
