Significant Decrease in Transparency of Acrylate-Epoxy-Phosphate-Distyrene Copolymer After Modification
Problem Phenomenon
The transparency of the acrylate-epoxy-phosphate-distyrene copolymer significantly decreases after modification, the haze increases, and it does not meet the requirements of transparent products
Cause Analysis
The refractive index of the added additives does not match that of the acrylate-epoxy-phosphate-distyrene copolymer
The additives are unevenly dispersed, producing scattering
The processing temperature is too high, and the additives degrade and discolor
The addition amount is too large, affecting the transparency
The crystallinity change affects the transparency
Solution
Select additives with matching refractive index
Ensure the additives are uniformly dispersed
Control the processing temperature to avoid additive degradation
Reduce the addition amount
Control the crystallization conditions
Key Takeaway
The decrease in transparency needs to be addressed from refractive index matching and dispersion
