Abstract
SE DESCRIBE UN PROCEDIMIENTO PARA LA OBTENCION DE PLASTICOS ESPUMADOS, UTILIZANDOSE UNA COMPOSICION LIQUIDA DE COADYUVANTES, QUE CONTIENE DIOXIDO DE CARBONO LIQUIDO A PRESION. ADEMAS DEL DIOXIDO DE CARBO LIQUIDO A PRESION PUEDEN UTILIZARSE TODOS LOS COADYUVANTES USUALES LIQUIDOS COMO ALCOHOLES, HIDROCARBUROS ALIFATICOS O CICLICOS, HIDROCARBUROS O ETERES HALOGENADOS. EL PROCEDIMIENTO SE UTILIZA EN PARTICULAR PARA LA SINTESIS DE PLASTICOS ESPUMADOS DE POLIETILENO, POLIESTIRENO O POLIURETANO. LAS COMPOSICIONES DE COADYUVANTES QUE CONTIENEN DIOXIDO DE CARBONO LIQUIDO A PRESION ESTAN INDICADAS TAMBIEN PARA LA FABRICACION DE ESPUMAS DE POLIURETANO DE UNO O VARIOS COMPONENTES. ADEMAS DEL DIOXIDO DE CARBONO LIQUIDO A PRESION, SE PUEDEN UTILIZAR TAMBIEN AQUI TODOS LOS COADYUVANTES USUALES LIQUIDOS COMO ETER, CETONA, HIDROCARBUROS ALIFATICOS O CICLICOS, HIDROCARBUROS O ETERES HALOGENADOS. ADEMAS TAMBIEN SE DESCRIBE UN PROCEDIMIENTO PARA LA OBTENCION DE ESTAS COMPOSICIONES DE COADYUVANTES.
