after 300 cycles of bayer abrasion testing the coated acrylic exhibits only 8 to 10 percent haze compared with 50 percent haze for uncoated acrylic after the same abrasion testing three grams of the polyvinylpyrrolidone of example i are dissolved in a solution comprising 35 grams of deionized water and 35 grams of methanol the solution is stirred for 15 minutes before adding 80 grams of methyltrimethoxysilane 8 grams of dimethyldiethoxysilane and 4 grams of glacial acetic acid the mixture is stirred for 2 hours at room temperature after which 0 2 grams of sodium acetate is added and the mixture is diluted with 50 grams of 2 propanol a stretched acrylic substrate is dip coated into the above composition and the coating is cured at 80 u00b0 c for 4 hours the cured coating is then subjected to bayer abrasion testing with the result of 3 5 percent haze after 300 cycles ultraviolet radiation exposure testing quv b results in only light cracking of the coating after 1732 hours three grams of the polyvinylpyrrolidone of the previous examples is dissolved in 55 grams of deionized water and 55 grams of methanol after stirring the solution for 15 minutes 80 grams of methyltrimethoxysilane 8 grams of dimethyldiethoxysilane and 4 grams of.
