Summary: A novel phosphorus/nitrogen-containing hyperbranched polyphenylphosphate (PHP) was synthesized and used to prepare transparent and flame retardant coatings for PMMA. Changing the content of PHP and ICPTMOS influenced the performance of PMMA coatings, with lower silicon content leading to reduced heat release and smoke production. By replacing a small amount of PHP with ICPTMOS, the fire resistance time of the coated PMMA sample was extended. This work provides an efficient strategy to enhance fire safety, transparency, and hardness of coatings simultaneously.
