Double monomer methodology

Vegetable oil-based hyperbranched polymers are prepared mainly by double monomer methodology (DMM), although single monomer methodology (SMM) may also be used. 

The double monomer methodology (DMM) is also used to obtain vegetable oil-based hyperbranched polymers. In this approach, direct polymerisation of two types of monomers or monomer pairs generates hyperbranched polymers. DMM can be divided into two main subclasses based on the selected monomer pairs and reaction pathways. In this technique, an A2 with a Bj monomer causes polymerisation, known as an A2 + B3 approach, or a monomer pair generates an in situ AB intermediate to form hyperbranched polymer. The last approach is known as couple monomer methodology (CMM).
