A functionalized processing aid represented by the following Chemical Formula 1 in which a silane-based compound and a cardanol-derived structure are combined:
- (R1)3Si—R2—Z-(E)n [Chemical Formula 1]
- in Chemical Formula 1,
- R1 is each independently a C1 to C10 linear or branched alkyl group or alkoxy alkyl group,
- R2 is a C1 to C20 linear or branched alkylene group,
- Z is nitrogen, sulfur, or oxygen,
- E is each independently hydrogen or a cardanol-derived structure represented by the following Chemical Formula 1-1
- at least one E is not hydrogen, and
- n is 1 or 2.
A method of preparing a functionalized processing aid, comprising the steps of:
- (a) preparing a mixture of a silane-based compound, epoxidized cardanol, and a solvent in the presence of a base;
- and
- (b) reacting the mixture to prepare a functionalized processing aid.
