Embodiment 1
[0017] (1) Add 1 g of glycidol to 200 mL of N,N-dimethylformamide, stir magnetically at room temperature for 20 min, then raise the temperature to 80 °C, then add 3 g of 9,10-dihydro-9- Oxa-10-phosphaphenanthrene-10-oxide, continue magnetic stirring until 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide is fully dissolved, continue magnetic stirring for 12 h , pour the reaction solution into a large amount of water, filter the precipitated solid, wash and dry to prepare 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide grafted glycidol.
[0018] (2) 10 parts of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide grafted glycidol, 0.05 parts of 1,3:2,4-di-p-methylbenzylidene sorbyl Alcohol, 5 parts of polypropylene grafted maleic anhydride, 0.5 parts of antioxidant and 100 parts of polypropylene were mixed with a high-speed mixer for 10 minutes, and the initial mixture was melt-blended through a twin-screw extruder at a melting temperature of 200 °C. The rotation speed of th...

[0022] (1) Add 1.5 g of glycidol to 350 mL of N,N-dimethylformamide, stir magnetically at room temperature for 40 minutes, then raise the temperature to 100 °C, then add 8 g of 9,10-dihydro-9-oxo hetero-10-phosphaphenanthrene-10-oxide, continue magnetic stirring until 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide is fully dissolved, continue magnetic stirring for 9 h, Pour the reaction solution into a large amount of water, filter the precipitated solid, wash and dry to prepare 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide grafted glycidol.
[0023] (2) 15 parts of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide grafted glycidol, 0.2 parts of 1,3:2,4-di-p-methylbenzylidene sorbyl Alcohol, 7 parts of polypropylene grafted maleic anhydride, 0.7 parts of antioxidant and 100 parts of polypropylene were mixed with a high-speed mixer for 20 minutes, and the initial mixture was melt-blended through a twin-screw extruder at a melting temperature of 230 °C. The rotation s...
Embodiment 3
[0027] (1) Add 2 g of glycidol to 500 mL of N,N-dimethylformamide, stir magnetically at room temperature for 60 min, then raise the temperature to 120 °C, then add 12 g of 9,10-dihydro-9- Oxa-10-phosphaphenanthrene-10-oxide, continue magnetic stirring until 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide is fully dissolved, continue magnetic stirring for 6 h , pour the reaction solution into a large amount of water, filter the precipitated solid, wash and dry to prepare 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide grafted glycidol.
[0028] (2) 20 parts of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide grafted glycidol, 0.4 parts of 1,3:2,4-di-p-methylbenzylidene sorbic acid Alcohol, 10 parts of polypropylene grafted maleic anhydride, 1 part of antioxidant and 100 parts of polypropylene were mixed with a high-speed mixer for 30 minutes, and the initial mixture was melt-blended through a twin-screw extruder at a melting temperature of 260 °C. The rotation speed of...
