Nettet9. jul. 2024 · Other polymers (generally those that are highly cross-linked) do not melt at all; these are known as thermosets. If they are to be made into molded objects, the … In brief, there are two categories of polymers based on their structure: linear polymers and cross linked polymers. The monomers of linear polymers have end-to-end links, resembling beads of a necklace. Hence, all thermoplastics belong to linear polymers and have no permanent cross-links between … Se mer 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 … Se mer A linear polymer is a thermoplastic polymer that consists of long-chain molecules.
