    摘要: Compounds of the general formula I′ in which R1 is H, C1-C12alkyl; C5-C12cycloalkyl; C2-C18alkyl which is interrupted by one or more O; SR4; OR5; or is a group of formula II or III R2, R21 and R3 independently of one another, are H or —Y-T as defined in claim 1, where T is a reactive group selected from OH, acryl- and methacryloxy and arylcarbonate groups, and further symbols are as defined in claim 1, are effective as crosslinking agents for polymeric networks, especially as in flexographic printing plates, coatings, and plastic containers or films. Further provided is a method of protecting the content of a clear or lightly colored plastic container or film against the deleterious effects of ultraviolet radiation, which method comprises permanently and covalently bonding one or more UV absorbing moieties of a durable s-triazine UV absorber via condensation to a suitable polymer component.

    摘要: The present invention discloses a process for the preparation of a stabilized polyester that is low in the generation of aldehydes which comprises reacting one or more diacids with one or more diols in an esterification process, and/or one or more diesters with one or more diols in a transesterification process in the presence of an effective amount of a stabilizer selected from the group consisting of (a) a polyhydric alcohol which is for example poly(ethylene-co-vinyl alcohol), poly(styrene-co-allyl alcohol), maltitol, isomalt, sorbitol, xylitol, sucrose, mucic acid dibutylester, mucic acid di(phenyl-1-ethyl)ester, pentaerythritol or dipentaerythritol; (b) a compound of the formula II which is for example di-iso-octyl-phosphinic acid; (c) a sterically hindered amine which is for example Tinuvin 123 or Tinuvin 622; (d) a polyacrylamide, an anionic acrylic polymer or a cationic acrylamide copolymer; or (e) a hydroxylamine and/or a nitrone. Such polyesters, for example PET, when extrusion compounded exhibit a lower residual acetaldehyde content than does PET alone when similarly treated. The invention pertains to any polyester used in the manufacture of bottles or containers which in turn are used to store consumer materials, especially food, pharmaceuticals, beverages and most especially water.
