Abstract
To provide a blended resin composition which comprises a thermoplastic resin which does not exhibit anisotropy in a molten state, such as a polyester resin, and a liquid-crystal polyester resin, and a resin composition which is reduced in delamination excellent in mechanical properties by blending 100 parts by weight of a resin component comprising 99 to 50 parts by weight of a thermoplastic resin (a) which does not exhibit anisotropy in a molten state and 1 to 50 parts by weight of a liquid-crystal polyester resin (b) capable of forming an anisotropic molten phase with 0.01 to 3.0 parts by weight of at least one silane compound (c) selected from among vinylalkoxysilanes, aminoalkoxysilanes and mercaptoalkoxysilanes.
Claims7
A synthetic resin composition comprised of 100 parts by weight of a resin component blend comprising:
- (a) 99 to 50 parts by weight of a thermoplastic polycarbonate resin which does not exhibit anisotropy in a molten state;
- (b) 1 to 50 parts by weight of a liquid-crystal polyester resin capable of forming an anisotropic molten phase;
- and
- (c) 0.01 to 3.0 parts by weight of at least one silane compound (c) selected from the group consisting of vinylalkoxysilanes, aminoalkoxysilanes and mercaptoalkoxysilanes;
- and wherein
- (d) said liquid crystal polyester resin (b) is in the form of fibers having an aspect ratio of 6 or greater dispersed in a matrix of the thermoplastic polycarbonate resin (a).
A process for producing a molding comprised of 100 parts by weight of a resin component blend comprising:
- (a) 99 to 50 parts by weight of a thermoplastic polycarbonate resin which does not exhibit anisotropy in a molten state;
- (b) 1 to 50 parts by weight of a liquid-crystal polyester resin capable of forming an anisotropic molten phase;
- and
- (c) 0.01 to 3.0 parts by weight of at least one silane compound (c) selected from the group consisting of vinylalkoxysilanes, aminoalkoxysilanes and mercaptoalkoxysilanes;
- wherein
- said method comprises injection molding the resin component blend at a temperature not lower than the fluidization-starting temperature of the liquid-crystal polyester resin (b) capable of forming an anisotropic molten phase and not lower than that of the thermoplastic polycarbonate resin (a) which does not exhibit anisotropy to form fibers of said liquid crystal polyester resin (b) having an aspect ratio of 6 or greater dispersed in a matrix of the thermoplastic polycarbonate resin (a).
