Abstract

The object of the invention is to provide a novel olefin-based molded product useful for various applications.An olefin-based molded product comprising a polymer including a structural unit of at least one polar olefin monomer represented by the general formula (I) CH2═CH—R2—Z(R1)n is provided. In the formula, Z is a hetero atom selected from the group consisting of nitrogen, oxygen, phosphorus, sulfur, and selenium; R1 is a substituted or unsubstituted hydrocarbyl group having 1 to 30 carbon atoms; n is an integer of 1 or 2 depending on the atomic species of Z; and R2 is a substituted or unsubstituted hydrocarbylene group having 2 to 20 carbon atoms.

First claim

The invention claimed is:

1. An olefin-based molded product comprising a polymer comprising a structural unit of at least one polar olefin monomer represented by the general formula (II):

wherein, Z is a hetero atom selected from the group consisting of nitrogen, oxygen, phosphorus, sulfur, and selenium; R 1 is a substituted or unsubstituted hydrocarbyl group having 1 to 30 carbon atoms; n is an integer of 1 or 2 depending on the atomic species of Z; R 3 is a hydrocarbylene group having 1 to 5 carbon atoms; R 4 is a halogen atom, a hydrocarbyl group having 1 to 10 carbon atoms, an alkylthio group having 1 to 10 carbon atoms, an alkylamino group having 1 to 10 carbon atoms, or an alkoxy group having 1 to 10 carbon atoms, and when R 4 is a hydrocarbyl group, the hydrocarbyl groups may bond together to form a condensed ring; and m is an integer of 0 to 4,
wherein the proportion of the polar olefin structural unit in the total structural units in the polymer is 20 mol % or more.

2. The olefin-based molded product according to claim 1 , wherein the polymer is a copolymer comprising an additional structural unit of at least one nonpolar olefin monomer.

3. The olefin-based molded product according to claim 2 , wherein the copolymer comprises an alternating sequence of the structural unit of at least one polar olefin monomer represented by the general formula (II) and the structural unit of at least one nonpolar olefin monomer.

4. The olefin-based molded product according to claim 1 , wherein the number average molecular weight of the polymer is 2.0×10 3 or more.

5. The olefin-based molded product according to claim 1 , which is a film.

6. The olefin-based molded product according to claim 1 , which is used as a self-healing material, which is a film or which is used as a shape memory material.

7. The olefin-based molded product according to claim 1 , which is used as a shape-memory material.
