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. Here, the monomer units have end-to-end links, resembling beads in a necklace. Polyethylene is an example of a linear polymer where … Se mer
