A rheology control agent for a curable composition includes: a diamide compound (A) and/or a hydrogenated castor oil (A′), the diamide compound (A) being obtained by condensation reaction between a diamine component (A1) and a monocarboxylic acid component (A2); and a polyamide compound (B) obtained by polycondensation of an amine component (B1) and a carboxylic acid component (B2). The amine component (B1) contains at least one amine selected from the group consisting of a diamine and a triamine having 2 to 54 carbon atoms. The carboxylic acid component (B2) contains at least one carboxylic acid selected from the group consisting of a dicarboxylic acid and a tricarboxylic acid having 4 to 54 carbon atoms. The polyamide compound (B) is obtained by polycondensation of at least one of the amine component (B1) and the carboxylic acid component (B2) containing polymerized fatty acids.

The present invention provides a film and/or a packaging bag from which contents that may be viscous are easily brought out, and exhibiting enough heat seal properties as well as superior anti-blocking effect and slipperiness. The sealant film has a seal layer consisting of a resin composition including the following (a) and (b), and the film satisfies the following (1) to (3). (a) Polyolefin-based resin; and (b) Silylated polyolefin resin, (1) An abundance ratio (Si/C) of silicon atoms Si to carbon atoms C included in the seal layer of 0.001 or more and 0.02 or less; (2) An abundance ratio (Si/C) of silicon atoms Si to carbon atoms C present at a surface of the seal layer of 0.05 or more and 0.2 or less; and (3) An arithmetic average roughness Ra of a surface of the seal layer of 0.1 μm or more and 0.5 μm or less

The present invention is directed to stabilizer compositions comprising at least one oxalanilide UV absorber, at least one hindered amine light stabilizer (HALS), at least one phenolic antioxidant and optionally further components. Said stabilizer compositions are preferably used in sealants or adhesives based on silyl-modified polymers (SMP). The invention is also directed to a polymer composition based on silyl-modified polymers (SMP) comprising the inventive stabilizer combination of oxalanilide UV absorber, hindered amine light stabilizer (HAL S) and phenolic antioxidant.

The invention relates to a method for producing a vessel closure for vessels comprising an opening that is to be closed by the vessel closure, an inner diameter of more than two cm and surrounds a polymer-based sealing element that is arranged in the vessel closure in such a manner that is sealingly rests on the opening of the vessel in the closed state. A polymer material becomes sufficiently free-flowing by warming and is applied to the vessel closure in the region of the sealing element that is to be produced, and optionally, is mechanically formed into the desired shape which it maintains after cooling. The invention also relates to a metal or plastic vessel closures for vessels for receiving drinks or food, and comprises a sealing insert, the material thereof being selected so that the migration of material components into the drink or food, that are a health risk, is prevented. The invention also relates to corresponding materials for said type of sealing inserts and to the use of specific polymers for producing the above-mentioned sealing inserts.
