ABSTRACT:
The polymer composite material is produced using no solvent and includes a rigid polymer (B) dispersed uniformly into a matrix (A) at the molecular level in a state of a copolymer (A/B and/or A'/B) thereby enhancing the interface bonding of the rigid polymer (B) to the matrix (A). The non-solvent method includes a step of polymerizing a thermoplastic polymer (A) and a monomer to form a rigid polymer (B) with no solvent in the molten and kneaded state to provide a copolymer (A/B and/or A'/B) in which the flexible molecular chains (A and/or A') are made up of the thermoplastic polymer to the rigid polymer (B) to reduce the stress concentrating sources of the rigid polymer dispersed microscopically at the molecular level in the thermoplastic polymer matrix and enhance the interface bonding between the rigid polymer (B) and the matrix (A).
