Abstract
Oggetto dell'invenzione è un copolimero casuale in forma di sale o di acido libero avente i seguenti. tipi ed i seguenti numeri di unità monomeriche: Formula I in cui M rappresenta idrogeno oppure un residuo di un glicol Polialchilenico idrofugo o polisilossano,R rappresenta un radicale alchilenico C2 - C6R1 rappresenta un gruppo alchilìco C1 - C20 cicloalchilico C 6- C9 o fenilico,x, y e z sono numeri compresi fra i e 100, m è un numero compreso fra 1 e 100, n è un numero compreso fra 10 e 100, con le condizioni che i) il rapporto fra x e (y+z) è compreso fra l:10 e 10:1 incluso,ii) il rapporto z:y è compreso fra 5:1 e 100:1, e iii) m+n = 15-100.I copolimeri sono utili come additivi in composizioni cementizie.
