CRYSTAL NUCLEATION AGENT FOR POLYOLEFIN

Title:

CRYSTAL NUCLEATION AGENT FOR POLYOLEFIN

Document Type and Number:

Japanese Patent JP3364004

Kind Code:

B2

Abstract:

PURPOSE: To provide a crystal nucleation agent composed mainly of a rosin metal salt, etc., effective for increasing the crystalllzation velocity of polyolefins and useful for giving a molded article having excellent mechanical properties and/or optical properties.
CONSTITUTION: This crystal nucleation agent for polyolefin is composed mainly of a metal salt (Na salt, K salt, Mg salt, etc.) of a rosin (e.g. natural rosin or modified rosin) or is a compound of formula (R", R2 and R3 are each independently H, an alkyl, a cycloalkyl or an aryl) and/or its metal salt. The agent is also effective for reducing the size of the crystal.
