Abstract
The present invention relates to an antistatic mixture comprising compounds of the formulae (I) and (II) R'--N--[(C.sub.n H.sub.2n)--OH].sub.2 (I) ##STR1## where n is 2 or 3 R.sup.1 is C.sub.8 -C.sub.22 -alkyl or -alkenyl or C.sub.8 -C.sub.22 -alkyl-CO-- and R.sup.2, R.sup.3 and R.sup.4 may be identical or different and are C.sub.8 -C.sub.22 -alkyl or -alkenyl and two of these radicals may be hydrogen, and where the mixing ratio of the compounds of formulae I and II is from 4:1 to 1:10 parts by weight, and to a process for preparing this mixture. This mixture is solid and is therefore easy to use in production, and is storage-stable and offers advantages in handling.
Claims12
A solid, storage-stable antistatic mixture consisting essentially of alkoxylated amines of the formula (I) and fatty acid glycerides of the formula (II)
- R.sup.1 --N--[(C.sub.n H.sub.2n)--OH].sub.2 (I) ##STR4## where n is 2 or 3
- R.sup.1 is C.sub.8 -C.sub.22 -alkyl or -alkenyl or C.sub.8 -C.sub.22 -alkyl-CO-- and
- R.sup.2, R.sup.3 and R.sup.4 may be identical or different and are C.sub.8 -C.sub.22 -alkyl or -alkenyl and two of these radicals may be hydrogen,
- and where the mixing ratio of the compounds of formulae I and II is from 4:1 to 1:10 parts by weight.
A process for preparing solid, antistatic mixtures of additives for plastics comprising:
- mixing alkoxylated amines of formula (I) as a first component
- R.sup.1 --N--[(C.sub.n H.sub.2n)--OH].sub.2 (I)
- with fatty acid glycerides of formula (II) as a second component ##STR5## wherein n is 2 or 3
- R.sup.1 is C.sub.8 -C.sub.22 -alkyl or -alkenyl or C.sub.8 -C.sub.22 -alkyl-CO-- and
- R.sup.2, R.sup.3 and R.sup.4 may be identical or different and are C.sub.8 -C.sub.22 -alkyl or -alkenyl and two of these radicals may be hydrogen, ps in a ratio of from 4:1 to 1:10 parts by weight, and heating the components of the formula (I) and of formula (II) until a homogeneous melt is obtained.
