Abstract

An additive composition containing a polymer (A) and an anti-static additive (B).
The polymer (A) has the following monomer components:
(i) one or more compounds of formula (I)

wherein R 1 is hydrogen or CH 3 ; and R 2 is a hydrocarbon group having 6 to 30 carbon atoms and is a straight-chain or branched-chain alkyl group, or an aliphatic or aromatic cyclic group;

(ii) one or more compounds of formula (II)

wherein R 1 has the meaning above and wherein R 3 is hydrogen or C 1 -C 22 alkyl; each R 4 is independently hydrogen or C 1 -C 22 alkyl; R 5 is hydrogen, a substituted or unsubstituted aliphatic or aromatic cyclic group, or a substituted or unsubstituted straight-chain or branched-chain alkyl group having 1 to 22 carbon atoms; n=0 or an integer from 1 to 22; and m is an integer from 1 to 30; and

(iii) one or more compounds of formula (III)

wherein R 6 , R 7 , R 8 , R 9 and R 10 are each independently hydrogen, a straight-chain or branched-chain alkyl group having 1 to 20 carbon atoms which may be substituted or unsubstituted, hydroxyl, NH 2 , or wherein two or more of R 6 , R 7 , R 8 , R 9 and R 10 may together form an aliphatic or aromatic ring system, which ring system may be substituted or unsubstituted.

The anti-static additive (B) is (iv) an olefin polysulfone and (v) a polymeric polyamine reaction product of epichlorohydrin and an aliphatic primary monoamine or an N-aliphatic hydrocarbyl alkylene diamine, or the sulfonic acid salt of the polymeric polyamine reaction product. The weight:weight ratio of the polymer (A) to the anti-static additive (B) in the additive composition is from about 1:1 to about 500:1.
