After having closed the vessel, the mixture was polymerized with agitation for 6.5 hours at 363 K and for 3 hours at 393 K. After a conversion of about 40 to 47% of styrene was achieved, 1.275 g of potassium peroxodisulfate in 100 ml of water and 298 g of tricalcium phosphate in 3 liters of water were added. After 4 hours at 363 K, 5.9 kg of an expanding agent mixture consisting of 75% by weight of n-pentane and 25% by weight of isopentane was forced into the vessel within 15 to 20 minutes.
