Problems solved by technology

In addition, since the PPO / PS alloy uses polystyrene PS as the blended resin, the PPO / PS alloy itself still has some inherent shortcomings of polystyrene PS, such as polystyrene PS weather resistance, solvent resistance, and environmental resistance. Poor performance such as stress cracking
In CN103044894B, it is mentioned that PPO / PS alloy has the problems of poor solvent resistance and poor environmental stress cracking resistance
[0005] But at present, there is no disclosure about cycloolefin polymer-polyphenylene ether COP / PPO alloy material
