Abstract
The present invention provides a polyolefin-based resin composition containing a crystal nucleating agent having a specific structure, which polyolefin-based resin composition has a superior transparency and whose crystallization is facilitated. The polyolefin-based resin composition is characterized by comprising, with respect to 100 parts by mass of a polyolefin-based resin, 0.01 to 1 parts by mass of at least one crystal nucleating agent selected from the group consisting of crystal nucleating agents each having a structure represented by one of the following Formulae (1) to (6):
Claims11
A polyolefin-based resin composition, characterized by comprising, with respect to 100 parts by mass of a polyolefin-based resin, 0.01 to 1 parts by mass of at least one crystal nucleating agent selected from the group consisting of
- a crystal nucleating agent (A) having a structure in which at least 4 carbamate groups represented by the following Formula (1) are linked via C1-C10 hydrocarbon group:
- (wherein, RI represents a hydrogen atom, a C1-C12 alkyl group which is optionally branched, a C3-C12 cycloalkyl group which is optionally substituted or a C6-C18 aryl group which is optionally substituted;
- and the plural R1s are each optionally different);
- a crystal nucleating agent (B) represented by the following Formula (2):
- (wherein, X1 is a C1-C5 alkylene group which is optionally branched;
- R2 to R5 independently represent one selected from the group consisting of a halogen atom, a C1-C4 alkyl group which is optionally substituted and/or is optionally branched and a C1-C4 alkoxy group which is optionally substituted and/or is optionally branched;
- and p, q, r and s independently represent an integer of 0 to 3 (provided that p and s are not 0));
- a crystal nucleating agent (C) represented by the following Formula (3):
- (wherein, R6 and R7 independently represent a C1-C10 alkyl group which is optionally branched and/or is optionally substituted, a C3-C12 cycloalkyl group which is optionally substituted or a C6-C20 aryl group which is optionally substituted;
- and X2 and X3 independently represent a single bond or a C1-C5 alkylene group;
- provided that the substituent(s) is/are not a hydroxyl group);
- a crystal nucleating agent (D) represented by the following Formula (4):
- (wherein, R8 and R9 independently represent a hydrogen atom, a C1-C12 alkyl group which is optionally branched and/or is optionally substituted, a C3-C12 cycloalkyl group which is optionally substituted or a C6-C18 aryl group which is optionally substituted;
- R8 and R9 optionally form a C6-C18 ring with a carbon atom at a terminal of the hydrazone structure;
- and X4 represents a C1-C10 alkylene group which is optionally branched and/or is optionally substituted, a C3-C12 cycloalkylene group which is optionally substituted or a C6-C20 arylene group which is optionally substituted);
- a crystal nucleating agent (E) represented by the following Formula (5):
- (wherein, R10 represents a hydrogen atom, a C1-C12 alkyl group which is optionally branched and/or is optionally substituted, a C3-C12 cycloalkyl group which is optionally substituted or a C6-C18 aryl group which is optionally substituted;
- and X5 represents a C1-C10 alkylene group which is optionally branched and/or is optionally substituted, a C3-C12 cycloalkylene group which is optionally substituted or a C6-C20 arylene group which is optionally substituted);
- and
- a crystal nucleating agent (F) represented by the following Formula (6):
- (wherein, R11 and R12 independently represent a C1-C6 alkyl group which is optionally branched).
