Abstract: A polyurethane urea composition and a preparation method thereof are provided. The method includes mixing and reacting an urea and an amine compound to obtain a polyurea oligomer, and mixing and reacting the polyurea oligomer and a cyclic carbonate compound to obtain a polyurethane urea composition having a repeating unit represented by formula I: —R2—U2—U1—U2—R2, wherein   [formula I] U1 is a is an integer of 1 to 10000, each U2 is independently each R1 is independently a C1 to C20 alkyl group, a C3 to C20 cycloalkyl group, a C8 to C20 alkylaryl group, a polyether group having a weight-average molecular weight of 100 g/mol to 10000 g/mol, or a combination thereof, and each R2 is independently an aliphatic group, a cycloaliphatic group, an aromatic group substituted by an alkyl or an unsubstituted aromatic group, an oligo polyether group, an oligo polyester group, or a combination thereof.

Abstract: An elastomer is provided, which is a product of reacting C4-12 lactam, poly(C2-4 alkylene glycol), C4-12 diacid, and multi-ester aliphatic monomer. The C4-12 lactam and the poly(C2-4 alkylene glycol) have a weight ratio of 20:80 to 80:20. The total weight of the C4-12 lactam and the poly(C2-4 alkylene glycol) and the weight of the C4-12 diacid have a ratio of 100:0.5 to 100:10. The total weight of the C4-12 lactam and the poly(C2-4 alkylene glycol) and the weight of the multi-ester aliphatic monomer have a ratio of 100:0.01 to 100:5.
