Abstract

Se describe una composicion de organopolisiloxano para espuma elastomeros. En una composicion organopolisiloxánica generadora de espuma elastomérica que comprende por lo menos un poliaciloxiorganopolisiloxano obtenido mediante funcionalizacion, mediante un poliaciloxisilano, de por lo menos un aceite reactivo que es un polisiloxanopolihidroxilado destinado a reaccionar en presencia de agua para formar el elastomero con formacion del ácido de formula R'COOH, en la cual R' representa un radical hidrocarburo exento de insaturacion alifática y que tiene de 1 a 5 átomos de carbono, un agente poroforo y eventualmente agua, el agente poroforo es por lo menos un carbonato ácido o neutro de un material alcalino o alcalinotérreo que. mediante reaccion con el ácido de la formula R'COOH de gas carbonico y de preferencia agua. Objetos particularmente juntas, así obtenidos y un equipo para la mezcla estática. Figura 2.
