Abstract
PURPOSE: A polyolefin resin containing a cationic surfactant and a foaming agent is foamed by heating, thereby producing foamed products with essentially no shrinkage with the passage of time, high dimensional stability and good surface smoothness by simple foaming operations.
CONSTITUTION: To a polyolefin resin containing cationic surfactants of formula I [R1 is 10W24C hydrocarbyl; X is (-[OH]m[R2]-O-)nH; R2 is H, 1W3C hydrocarbyl; m is less than 5; n is less than 10; Y is H, 1W24C hydrocarbyl] is incorporated a foaming agent and the foaming is effected. The cationic surfactant used is, e.g., polyoxyethylene myristylamine, stearylamine acetate salt.
