Abstract

"PROCESSO PARA A PREPARAçãO DE UM HIDROGEL, E, HIDROGEL". A presente invenção refere-se aos hidrogéis polimerizados e aos processos para a preparação de tais hidrogéis, em particular de adesivos de hidrogel que são capazes de aderir em pele de mamífero e podem ser usados em vários produtos para o cuidado pessoal, tais como artigos de manuseio de resíduo, e uma variedade de artigos funcionais a serem usados por um humano. Os hidrogéis aqui descritos são caracterizados por quantidade muito baixa de monómeros iniciais residuais, de impurezas, e/ou de subprodutos que poderiam ser formados durante a polimerização. Especificamente, os hidrogéis são preparados pela adição de removedores e/ou de agente de transferência de cadeia antes da polimerização. Tem sido verificado que com a adição dos mesmos removedores as propriedades de material do hidrogel polimerizado diferem das propriedades de géis polimerizados sem o removedor. Isto é devido ao fato de que estes removedores específicos também atuam como agentes de transferência de cadeia na polimerização radicalar. Outros estudos mostraram que também os agentes de transferência de cadeia, que não são removedores para monómero(s) residual(ais), impurezas ou subprodutos influenciam as propriedades de material do adesivo de hidrogel polimerizado.
