WebThe chain effect of polymer is the kernel of the precise synthesis of complex polymer compounds and the development of polymer science. Nucleic acids, a special type of polyester, can form supramolecular polymers via hydrogen bonds among corresponding bases. We focused on the precise control of polymer chains and proposed the concept of … WebThe structure is basically a linear 1 dimensional strong bonding networks (though there can be some branching with a side-chain group, but very little cross-linking). The polymer molecules are held together by weak intermolecular forces and NOT by the strong chemical bonds holding the carbon chain 'backbone' together.
