Obvious transparency decline of modified styrene-butadiene copolymer
Fenómeno del problema
The transparency of modified styrene-butadiene copolymer declines obviously, haze increases, and it does not meet transparent product requirements
Análisis de la causa
The refractive index of added additives does not match that of styrene-butadiene copolymer
Uneven additive dispersion produces scattering
Processing temperature is too high and additives degrade and discolor
Excessive addition amount affects transparency
Crystallinity changes affect transparency
Solución
Select additives with matching refractive index
Ensure uniform additive dispersion
Control processing temperature to avoid additive degradation
Reduce the addition amount
Control crystallization conditions
Conclusión clave
Transparency decline needs to be addressed from refractive index matching and dispersion
