Abstract
PROCESSO DE PREPARAçãO DE COPOLìMERO DE áLCOOL VINìLICO-N-VINILAMINA ALTAMENTE SOLúVEL EM áGUA, COPOLIMERO OBTIDO E SEU USO. Dito copolímero com um grau de hidrólise superior a 93%, sendo que o dito processo compreende uma reação de hidrólise de um copolímero de álcool vinílico-N-vinilformamida com um hidróxido de metal alcalino em metanol, caracterizado pelo fato de o dito processo ser realizado com mais de 1,5 mole de hidróxido de metal alcalino por mole de unidades de N-vinilformamida e sem a adição de água. Trata-se também a presente invenção de um copolímero de álcool vinílico-N-vinilamina altamente solúvel em água obtido por meio deste processo e o uso do mesmo.
