Abstract
A polyacetal resin composition comprises a polyacetal resin as the matrix, (A) 0.01 to 2.0 percent by weight of a stabilizer selected from a benzotriazole compound, a benzophenone compound and an aromatic benzoate compound and (B) 0.01 to 2.0 percent by weight of a hindered amine compound and is improved in whetherability.
Claims7
A polyacetal resin composition of improved crack resistance which comprises a polyacetal resin as the matrix, (A) 0.01 to 2.0 percent by weight of a stabilizer selected from a benzotriazole compound and (B) 0.01 to 2.0 percent by weight of a hindered amine compound which is a piperidine derivative having stereohindered groups;
- the combination of (A) and (B) having a synergistic effect in stabilizing said polyacetal resin against weathering yet having little effect on physical/mechanical properties and heat stability of said polyacetal.
