Abstract
The present invention relates to an additive composition including a counteragent, and more particularly, to an additive composition for preparation of polyolefins, which improve flowability of a nucleating agent and exhibits excellent transparency, by applying a counteragent of a specific structure to a sorbitol nucleating agent which is an additive used in preparation of polyolefins.
Claims8
An additive composition comprising:
- (a) a sorbitol acetal compound;
- and
- (b) a counteragent represented by Formula 1:
- (MII)4+x(MIII)2 (OH)12(An−)2/n·mH2O [Formula 1]
- wherein MII is at least one 2-valent metal selected from the group consisting of Mg, Ca, Co, Zn, and Ni;
- MIII is a 3-valent metal selected from the group consisting of Al, Fe, Co, Mn, and Ti;
- An− is an anion having a valence of n and is selected from the group consisting of HPO42−, NO3−, SO42−, OH−, F−, Cl−, and Br−;
- and
- 0≦x≦4 and m≧0,
- wherein the counteragent of Formula 1 has an index of refraction from 1.47 to 1.62.
