UN PROCEDIMIENTO PARA PREPARAR UNA ESPUMA DE EXCELENTE TENACIDAD A PARTIR DE POLIMEROS EXPANDIBLES ESTIRENICOS Y ETILENICOS Y UN AGENTE DE EXPANSION. |
摘要 |
<p>Novel foamed thermoplastic resins are disclosed. The foam includes an ionically associated blend containing at least about 60 weight % of a metal salt of a styrene-acrylic acid copolymer and at least 1 weight % of a metal salt of an ethylene-acrylic acid copolymer. The foams typically are prepared by extruding a ternary mixture of a styrene-acrylic acid copolymer, an ethylene-acrylic copolymer and an alkali metal bicarbonate which functions as the foaming agent. The ionically associated blends included in the foam are believed to be novel compositions of matter.</p> |
