Title:
ROSIN-BASED MOLECULE CRYSTAL, NUCLEATING AGENT FOR POLYOLEFIN RESIN, POLYOLEFIN RESIN COMPOSITION AND ITS MOLDED PRODUCT
Document Type and Number:
Japanese Patent JP3921750
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject new crystal excellent in transparency, gloss, rigidity and moldability and useful as a nucleating agent for polyolefin resins by forming the crystal from a rosin-based resin acid containing dehydroabietic acid and a rosin-based resin acid alkali metal salt.
SOLUTION: This crystal is formed from (A) dehydroabietic acid or a rosin- based resin containing the dehydroabietic acid as an essential component, and (B) at least one kind of rosin-based resin acid alkali metal salt selected from the group consisting of the lithium salt, sodium salt and potassium salt of the component A in an A/B molar ratio of 1:1, preferably 3:1.
