Upon extended aging at room temperature, ethylene/methacrylic acid (E/MAA) ionomers develop an endotherm near 50 °C in their differential scanning calorimetry traces. The origin of this low-temperature endotherm has been the subject of considerable debate, in part because direct structural probes have been little applied to its study. Here, we use in situ small-angle X-ray scattering and wide-angle X-ray diffraction to show that this endotherm reflects the melting of thin polyethylene crystals, which gradually develop following primary crystallization. These secondary crystals form within the amorphous layers separating primary crystals. When the framework of primary crystals is oriented by crystallization during flow, the secondary crystals follow this orientation, indicating that the secondary crystals are not isometric fringed micelles but instead have a substantial lateral extent.

Endotherm
Yes, the homeothermic endotherm is able to regulate its body temperature internally, regardless of external conditions.
A rabbit is a mammal, and as such it is an endotherm. He produces his own heat from the energy he gets from his food, and has no need of an extern source like the sun or a radiating lightbulb.
An endotherm is an animal that maintains its body temperature by producing heat from energy from food. Ectotherms get their heat only from the environment. The honey badger is a mammal, and, like all mammals, is an endotherm.

Ectothermic means its cold bloodedendothermic means that its warm bloodedOne trait that distinguishes the major groups of vertebrates from one another is the way in which they control their body temperature. Most fish, amphibians, and reptiles have body temperatures that are close to the temperature of their environment.2 Fish, amphibians, and reptiles are ectotherms. An ectotherm is an animal whose body does not produce much internal heat. Its body temperature changes depending on the temperature of the environment. For example, when a turtle is lying in the sun on a riverbank, it has a higher body temperature than when it is swimming in a cool river. Ectotherms are sometimes called "cold-blooded," but that is misleading. The blood of ectotherms is often quite warm.3 In contrast to the turtle, a beaver would have the same body temperature whether it was in cool water or on warm land. The beaver is an endotherm. An endotherm is an animal whose body controls and regulates its temperature by controlling the internal heat it produces. An endotherm's body temperature usually does not change much, even when the temperature of its environment changes. Mammals and birds are endotherms. They have a stable body temperature that is typically much warmer than their environment. Endotherms are often called "warm-blooded" animals.
A sloth is an endotherm, which means it can regulate its own body temperature internally. This allows sloths to maintain a relatively stable body temperature, even if the external environment changes.
