WebApr 9, 2024 · We can say that cross-linked polymers are those polymers that are obtained when a cross-link bond is formed between the monomeric units. The cross-linked polymer leads to the formation of long chains which can be either branched or linear, that can create covalent bonds between the polymeric molecules. WebGPAs are categorized into five classes based on structural considerations. 2 Classes I–IV contain either biaryl or bisaryl ether crosslinks involving tyrosine, 4-hydroxphenylglycine (Hpg), 3,5-dihydroxyphenylglycine (Dpg), or chlorinated derivates of Tyr and Hpg. präsentation in teams halten
