Web3 de abr. de 2024 · An addition polymer is a polymer formed by simply linking the monomers with no co-generation of other products. These polymers are generally made from molecules having carbon-carbon double bonds which means addition polymers are prepared from alkenes. They are also called chain growth polymers. Web13 de abr. de 2024 · While cross-links are formed in the foams, long, linear chains are present in CE and TPU. One factor here is the use of the blowing agent water in the production of the foams. Water leads to a change in the molecular structure since ureas and biurets are formed in addition to urethane bonds, which crosslink the chains.
