Abstract
The present invention relates to the modification of surface properties of particulate, linear, sheet-like, or three-dimensional structures using alkoxylated polyvinylamines. The invention further relates to novel alkoxylated polyvinylamines, and also to a process for their preparation.
Claims15
Synthetic fibers or sheet-like, or three-dimensional structure comprising, at least on its surface, a hydrophilicizing amount of at least one alkoxylated polyvinylamine, where at least some of the polyvinylamine nitrogen atoms bear radicals of the formula I:
- [Parenopenst]CH2—CR1R2—O[Parenclosest]m[Parenopenst]CH2—CHR3—O[Parenclosest]nH (I)
- where R1, R2, R3, m, and n are as follows:
- R1 is C2-C28-alkyl, C2-C28-alkenyl, C6-C16-aryl, or C7-C16-arylalkyl,
- R2 is hydrogen or methyl,
- R3 is hydrogen or methyl,
- m is an integer from 1 to 20, and
- n is 0 or an integer from 1 to 100.
A structure as claimed in any of the preceding claims, in the form of a linear or sheet-like textile structure.
A structure as claimed in any of the preceding claims, in the form of a plastic film or of a plastic molding.
An alkoxylated polyvinylamine, where at least some of the polyvinylamine nitrogen atoms bear radicals of the formula I
- [Parenopenst]CH2—CR1R2—O[Parenclosest]m[Parenopenst]CH2—CHR3—O[Parenclosest]nH (I)
- where R1, R2, R3, m, and n are as follows:
- R1 is C2-C28-alkyl, C2-C28-alkenyl, C6-C16-aryl, or C7-C16-arylalkyl,
- R2 is hydrogen or methyl,
- R3 is hydrogen or methyl,
- m is an integer from 1 to 20, and
- n is 0 or an integer from 1 to 100,
- and where the value {overscore (m)} of the variables m in the side chains of the formula I, averaged over the number of amino groups in the polyvinylamine, is at least 1.1, and where the value n of the variables n in the side chains of the formula I, averaged over the number of amino groups in the polyvinylamine, is in the range from 0.1 to 100.
