kjedeforlengere
Kjedeforlengere, sometimes referred to as chain extenders, are chemical compounds used in polymer chemistry. Their primary function is to increase the molecular weight of polymers, particularly polyurethanes and polyesters. This is achieved by reacting with pre-polymers, which are shorter polymer chains with reactive end groups.
The process involves the kjedeforlenger reacting with the end groups of these pre-polymers, linking them together
Common examples of kjedeforlengere include diols and diamines. Diols, which contain two hydroxyl (-OH) groups, react
The use of kjedeforlengere is crucial in tailoring the performance of various polymeric materials for applications
