Abstract
A novel amine-free antistatic agent comprising the reaction product of diethanolamine and a fatty acid or fatty acid ester, neutralized with a strong acid is disclosed, along with plastic composition treated with said antistatic composition, as well as a method for making the antistatic composition and methods for using it to produce plastic articles with antistatic properties.
Claims12
A substantially amine-free antistatic composition comprising the diethanolamide reaction product of a fatty acid or fatty acid ester and diethanolamine, which reaction product has been further neutralized with strong acid, wherein said fatty acid or fatty acid ester has the general formula RCOOR', wherein R is an aliphatic hydrocarbon radical or mixture of aliphatic hydrocarbon radicals comprising from 5 to 23 carbon atoms, and R' is an alkyl radical.
A composition having antistatic properties comprising an organic polymer and the diethanolamide reaction product of a fatty acid or fatty acid ester and diethanolamine, neutralized with a strong acid, wherein the fatty acid or fatty acid ester has the general formula RCOOH or RCOOR', wherein R is an aliphatic hydrocarbon radical or mixture of aliphatic hydrocarbon radicals comprising from 5 to 23 carbon atoms, and R' is alkyl radical.
An essentially amine-free antistatic composition comprising the amide reaction product of diethanolamine and a fatty acid or fatty acid ester of the general formula RCOOH or RCOOR', wherein R is an aliphatic hydrocarbon radical or mixture of aliphatic hydrocarbon radicals comprising from 5 to 23 carbon atoms, and R' is an alkyl radical, and the neutralized reaction product of diethanolamine and a strong acid.
