Abstract: The present invention relates to polymerized hydrogels and processes to make such hydrogels, in particular hydrogel adhesives which are capable of attaching to mammalian skin and can be used in various personal care product s, such as waste-management articles, and a variety of functional articles to b e worn by a human. The hydrogels described herein are characterized by very lo w amount of residual starting monomers, impurities, and/or by-products that could be formed during polymerization. Specifically, the hydrogels are made by adding scavengers and/or chain transfer agent prior to polymerization.It has been found, that upon addition of same scavengers the material properties of the polymerized hydrogel differ from the properties of gels polymerized without the scavenger. This is due to the fact, that these specific scavenge rs act also as chain transfer agents in the radical polymerization.Further studies showed that also chain transfer agents, that are no scanvengers for residual monomer(s), impurities or byproducts influence the material properties of the polymerized hydrogel adhesive.
