好像没有什么差异。好像合成材料领域用polymer多些。应该与这个概念出现时不同的人用词有关吧！ 下面是维基的解释（节选）： A macromolecule is a very large molecule commonly created by polymerization of smaller subunits. In biochemistry, the term is applied to the three conventional biopolymers (nucleic acids, proteins, and carbohydrates),[2] as well as non-polymeric molecules with large molecular mass such as lipids and macrocycles. The individual constituent molecules of polymeric macromolecules are called monomers 。 A polymer (/ˈpɒlɨmər/[2][3]) (poly-, "many" + -mer, "parts"  is a large molecule, or macromolecule, composed of many repeated subunits. Because of their broad range of properties,[4] both synthetic and natural polymers play an essential and ubiquitous role in everyday life.[5] Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass relative to small molecule compounds produces unique physical properties, including toughness, viscoelasticity, and a tendency to form glasses and semicrystalline structures rather than crystals. |

Macromolecules are molecules made of smaller subunits. Polymers are macromolecules made of repeating subunits. For example, a protein is both a macromolecule and a polymer since it is made of repeating units of amino acids. Theorically, there are no limits to how many amino acids there can be in a protein molecule. A tryglyceride is a macromolecule but not a polymer. Tryglycerides are made of a glycerol binded with three fatty acids. There are no repeating units. So tryclycerides are not polymers.——Gt.
