A resin composition comprises a polylactic acid resin (A) 75-10 wt %, an aromatic polycarbonate resin (B) 25-90 wt % and a polymer compound to which a glycidyl compound or an acid anhydride is grafted or copolymerized (D) 1-50 wt parts with respect to 100 wt parts of the total of the component (A) and the component (B).

Resin composition and molded article comprising the same

A resin composition in which a polylactic acid resin (A) 95-5 wt %, an aromatic polycarbonate resin (B) 5-95 wt %, and, with respect to 100 wt parts of the total of the (A) and the (B), at least one compatibilizer selected from a polymer compound containing an acrylic resin or styrene resin unit as a graft (C), a polymer compound to which a glycidyl compound or an acid anhydride is grafted or copolymerized (D) and an oxazoline compound, an oxazine compound and a carbodiimide compound (E) are compounded.

A flame-retardant polybutylene terephthalate resin composition wherein (A) 20-70% by weight of a polybutylene terephthalate resin or a mixture of a polybutylene terephthalate resin and a polyethylene terephthalate resin, (B) 1&#x2013;20% by weight of a vinyl based resin, (C) 1&#x2013;20% by weight of a phosphoric acid ester, (D) 1&#x2013;30% by weight of a salt of a triazine based compound and cyanuric acid or isocyanuric acid, and (E) 0.1&#x2013;5% by weight of an alkaline earth metal compound are compounded, and formed articles thereof have high degrees of flame retardancy and tracking resistance, and are unlikely to allow occurrence of metal pollution or deterioration in hydrolysis resistance due to a phosphoric acid ester, and therefore are suitable for machine component parts, electrical/electronic component parts, and automotive component parts.

Methods of improving the thickness and characteristics of galvanizing processes are disclosed. Several methods are disclosed which promote growth of the .zeta. layer in a double dipping galvanizing process. In one process a metal article is dipped in a molten-zinc bath at 430.degree.-480.degree. C. The article is then air-cooled or semi-air-cooled before it is dipped in a molten zinc bath containing no less than 0.1% aluminum at 390.degree.-460.degree. C. In another method, after molten-zinc-plating a metal article at 480.degree.-500.degree. C., the article is plated in a molten zinc bath containing no less than 0.1% of aluminum at 390.degree.-460.degree. C. In a third method, the surface of a metal article is blasted to form a surface having a roughness of at least 20 .mu.m before plating the article in a molten-zinc bath at 430.degree.-480.degree. C. The article is then plated in a molten zinc bath containing no less than 0.1% of aluminum at 390.degree.-450.degree. C.
