Polymer composition and molded products formed thereof

1. A polymer composition comprising:

a first base polymer (A) containing at least a thermoplastic polymer;

a second base polymer (B) containing at least a thermoplastic polymer and not having compatibility with the first base polymer (A); and

an additive (C) comprising an oil containing at least a substance not having compatibility with any of the first base polymer (A) and the second base polymer (B), the additive (C) being in the form of liquid or slurry at the lower of a pyrolysis temperature of the first base polymer (A) and a pyrolysis temperature of the second base polymer (B),

wherein (A), (B) and (C) are phase-separated from each other, and interfaces each located between two of phases of (A), (B) and (C) contacting each other form three-dimensional continuous parallel interfaces,

said three-dimensional continuous parallel interfaces referring to each of the opposite sides of a layer which separates two regions in a gyroid structure, said gyroid structure referring to an interconnected structure in which a continuous layer periodically extends throughout a space, dividing the space into two regions,

wherein components (A), (B) and (C) form a parallel layer having a gyroid structure, and (A) and (B) occupy two respective regions separated by (C), wherein said continuous parallel interfaces include an interface α between (B) and (C) and an interface β between (A) and (C) of a layer formed of (C), and an interface γ between (A) and (B) wherein the interfaces α, β, and γ are parallel with each other, and three-dimensionally and continuously extend throughout space.

8. The molded product of claim 7 , wherein the molded product is a filter including a melt blown nonwoven fabric or a multilayer structure of a melt blown nonwoven fabric.

9. A molded product obtained by diluting the polymer composition of claim 1 with one of (A), (B) and polymers having compatibility with (A) or (B), and molding the dilution of the polymer composition.

10. The molded product of claim 9 , comprising a film made of (C) and having a thickness from 0.001 μm to 2 μm on a surface thereof.

11. A fluid having fluidity, wherein the fluid contains a mixture of the polymer composition of claim 1 in the form of powder and a liquid.

12. An ink comprising the polymer composition of claim 1 .

13. A paint comprising the polymer composition of claim 1 .
