    • The invention relates to the use of oligomeric carbodiimides containing at least one heterocyclic end group as stabilizers for polymers. The oligomeric carbodiimides can be compounds of the general formula (I), in which A1, A2 are identical or different and represent hydrocarbon groups with 2 to 20 carbon atoms independently of each other; B1, B2 are identical or different and represent heterocycles, C1-C30 alcohols, poyletherols, polyesterols, amines, polyetheramines, polyesteramines, thioalcohols, polyetherthiols, polyesterthiols independently of each other; R1, R2 are identical or different and represent (A) independently of each other; and n represents a whole number ranging from 2 to 100; wherein A1, A2, B1 and B2 can each be substituted with C1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkinyl, C1-C20 alkoxy, carbonyl oxygen (=O), or halogen at any position with the proviso that at least one substituent of B1 or B2 is a heterocyclic end group. The invention further relates to methods for stabilizing polymers against hydrolysis using oligomeric carbodiimides.

    • 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.
