| Abstract: | The paraffins-polystyrene microspheres were synthesized by the technology of suspension polymerization. The mixture ratio and volume of compound substance and the type and volume of dispersant agent were studied to find the influence on the site distribution of the the paraffins-polystyrene microspheres during the cause of the synthesis. Results show that it was available for synthesizing little size paraffins-polystyrene micro spheres at high productivity when polystyrence were used as disperser, and it was the best mixture ratio and volume at 1:2.5 and 150 mL in the system of suspension polymerization. |
