WebMay 17, 2024 · What is a Cross Linked Polymer? A cross linked polymer is a polymer that has chains linked together by a network of covalent bonds. Cross links can be short or long, but in most of the polymers, these bonds are short. Thermosets and elastomers have cross links. The properties of cross linked polymers mainly depend on the degree of cross linking. Web70 Higher cross-linking density reduces the average void size in the polymer matrix, yielding more saltselective and less water-permeable membranes. 71 Dense polymer membranes …
