Abstract:
A pseudo cross-link resin composition comprising at least two polymers;wherein the resin composition is obtained by mixing a polymer A that has an atomic group capable of forming an intermolecular hydrogen bond in a molecular side chain and/or at a molecular tail end of the polymer molecule, and a polymer B that has an atomic group capable of forming an intermolecular hydrogen bond in a molecular side chain and/or in a molecular skeleton of the polymer molecule; wherein the polymer A that has an atomic group capable of forming an intermolecular hydrogen bond in a molecular side chain and/or at a molecular tail end is a vinylic polymer and/or copolymer that has a carboxyl group in a molecular side chain and/or at a molecular tail end, and the polymer B that has the atomic group capable of forming an intermolecular hydrogen bond in a molecular side chain and/or in a molecular skeleton is a vinylic polymer and/or copolymer having at least one nitrogen atom in a molecular side chain and/or a molecular skeleton; wherein one of the vinylic polymer and/or copolymer that has a carboxyl group in a molecular side chain and/or at a molecular tail end and the vinylic polymer and/or copolymer that has at least one nitrogen atom in a molecular side chain and/or in a molecular skeleton has a glass transition temperature equal to or lower than room temperature and the other has a glass transition temperature equal to or higher than room temperature; wherein when the polymer A and the polymer B or copolymers thereof are mixed together, the intermolecular hydrogen bond is formed therebetween; and wherein when these vinylic polymers and/or copolymers are mixed, the pseudo cross-link resin composition can be endowed with flexibility.
