| description | An object of the present invention is to provide a molded product that is formed of a plurality of portions containing 4-methyl-1-pentene polymers in contact with each other and has good bonding strength between the portions and good scratch resistance and stain resistance of the molded product, and to provide a method for producing the molded product. A molded product according to the present invention includes a portion (1) formed of a composition (X) containing a particular 4-methyl-1-pentene (co)polymer (A) having a melting point (Tm) measured by DSC of within the range of 200 to 250°C and a particular 4-methyl-1-pentene copolymer (B) having no observed melting point (Tm) or having a melting point (Tm) of within the range of 100 to 199°C, the melting point (Tm) being measured by DSC, wherein a content of the (co)polymer (A) is 60 to 95 parts by mass of based on a total of 100 parts by mass of the (co)polymer (A) and the copolymer (B), and a portion (2) that contains the 4-methyl-1-pentene (co)polymer (A) and is formed in contact with the portion (1). |
