Abstract
In a polycarbonate resin composition containing a polycarbonate resin and a polycarbosilane compound, the use of the polycarbosilane compound modifies the surface properties of the polycarbonate resin composition without adversely affecting the intrinsic characteristics of the polycarbonate resin, such as transparency, heat resistance, and mechanical properties, e.g., impact resistance. A polycarbonate resin composition containing 100 parts by mass of a polycarbonate resin, 0.001 to 1 part by mass of a metal salt compound, and 0.005 to 5 parts by mass of a polycarbosilane compound has significantly improved flame resistance and high transparency and causes markedly reduced outgassing and mold fouling, without losing impact resistance and heat resistance.
Claims13
A thermoplastic resin composition, comprising:
- a thermoplastic resin;
- a fluoropolymer;
- and
- a fluoropolymer dispersant,
- wherein the fluoropolymer dispersant comprises a polycarbosilane compound,
- wherein the polycarbosilane compound has a repeating unit represented by the following formula (4) and a number-average molecular weight of 100 to 20000:
- in the formula (4), R1and R2each independently represent a monovalent hydrocarbon group, a hydrogen atom, or a silyl group;
- a and b each independently represent 0 or 1;
- A1 represents a divalent hydrocarbon group having 1 to 12 carbon atoms;
- p and q each independently represent an integer of 1 to 8;
- and R1s, R2s, and A1s in all the repeating units may each be the same or different.
