摘要:
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 products, such as waste-management articles, and a variety of functional articles to be worn by a human. The hydrogels described herein are characterized by very low 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 scavengers 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.

摘要:
The invention relates to a method for producing discrete patterns of a sticking coating on a substrate, comprising the following steps: (a) moving continuously or discontinuously the substrate in a conveyor device; (b) flatly applying a low viscosity, polymerizable and/or cross-linkable precursor material of a sticking material through at least one opening substantially configured in the form of a slot of a movable application device on the substrate, whereby a pattern is produced by moving the application device relative to the substrate and (c) the applied precursor material is polymerized and/or crosslinked downstream of the application area.
摘要:
The present invention relates to hydrogel adhesives which are capable of attaching to mammalian skin, exhibit excellent attachment and painless removal properties, and which show excellent stability upon storage at room temperature or even at elevated temperatures and for longer periods of time. The adhesive hydrogel described in the present invention can be used as body adhesive in products for e.g. personal care, medical devices, beauty care and a variety of functional articles to be worn by a human. The hydrogel adhesive of the invention comprises 10-60 wt.% of a cross-linked hydrophilic polymer, 5-80 wt.% of a water-soluble non-ionic humectant, and from about 10-85 wt.% water, wherein the hydrophilic polymer comprises at least 80 mole % of one or more weak-acid monomer units having a pKa above 3, the weak-acid monomer being more than 60 mole % in its salt form, the level of monomer in acid form in said hydrophilic polymer not exceeding 50 mole % of all monomer units and the hydrogel adhesive having a peel strength on PET of 0.3 to 5.0 N/cm and a stability index measured after 14 days SIx14 below 0.50, preferably below 0.20, most preferably below 0.10.
