Abstract
PURPOSE: To prepare the titled composition having optimum decomposition temperature for the processing, and giving a pure white foamed article containing uniform and fine pores, by compounding a specific organic foaming agent with a hardly water-soluble product obtained by melting urea, as a foaming assistant.
CONSTITUTION: The objective composition is prepared by compounding (A) 100pts.wt. of dinitrosopentamethylenetetramine as an organic foaming agent with (B) pref. 50W200pts.wt. of a product obtained e.g. by melting urea, heating the molten urea for 5hr until the increase in turbidity and viscosity occurs, pouring water to the heat-treated product, followed by washing with water and drying. Other foaming agents such as azodicarbonamide may be incorporated to the composition.
