PROBLEM TO BE SOLVED: To prevent the occurrence of defects such as cracks in a molded body by specifying the amts. of polyacetal resin and modified polyolefin resin and the total amt. of the resins. SOLUTION: This compsn. contains a binder contg. 10-90vol.%, in total, of 5-60vol.% polyacetal resin and 5-85vol.% modified polyolefin resin. In the case of <10vol.% total amt. of the resins, a molded body is liable to deformation in a dewaxing process by heating. In the case of >90vol.%, the flowability of this compsn. deteriorates and injection molding at the time of forming a green molded body is not smoothly carried out. Since the binder is used, dewaxing by heating proceeds rapidly and production efficiency can be enhanced. |
