    Abstract: A molded product with excellent transparency can be obtained by using a polymer (D) obtained by suspension polymerization of a monomer mixture (1) containing (a) to (c) below:
    (a) 5-60 mass% of a specific macromonomer;
    (b) 5-60 mass% of the raw material monomer of a homopolymer (B) that has a solubility parameter that is different by 0.25 or more from the solubility parameter of the macromonomer (a); and
    (c) 10-80 mass% of the raw material monomer of a homopolymer (C) that has a solubility parameter that is different by less than 0.25 from the solubility parameter of macromonomer (a).
