Abstract
A resin composition includes a polyester capable of forming a crystal structure, and a substance represented by the following general structural formula (1), the substance represented by the following general structural formula (1) has a dehydration-condensed structure of two molecules of natural product-derived α-amino acids or a substitution structure thereof, and the two molecules of α-amino acids are not simultaneously glycine. In the above general structural formula, R1, R2, R3, and R4 indicate groups or substituent groups thereof bonded to the α carbons of the α-amino acids.

A resin composition comprising:
- a polyester capable of forming a crystal structure;
- and
- a substance represented by the following general structural formula (1),
- wherein the substance represented by the following general structural formula (1) has a dehydration-condensed structure that is an anhydride of two molecules of natural product-derived α-amino acids or a substitution structure thereof, and the two molecules of α-amino acids are not simultaneously alanine or glycine and at least one amino acid is selected from phenylalanine or valine,
- where R1, R2, R3, and R4 indicate groups or substituent groups thereof bonded to the α carbons of the α-amino acids.
A resin molded product formed from a resin composition which comprises:
- a polyester capable of forming a crystal structure;
- and
- a substance represented by the following general structural formula (1),
- wherein the substance represented by the following general structural formula (1) has a dehydration-condensed structure that is an anhydride of two molecules of natural product-derived α-amino acids or a substitution structure thereof, and the two molecules of α-amino acid molecules are not simultaneously alanine or glycine and at least one amino acid is selected from phenylalanine or valine,
- where R1, R2, R3, and R4 indicate groups or substituent groups thereof bonded to the α carbons of the α-amino acids.
