Platic modifier about B2 specification introduce

B2 is prepared by reactive grafting of maleic anhydride onto polypropylene. 

B2 is a maleic anhydride grafted polypropylene (PP) copolymer, which is commonly used as a coupling agent and compatibilizer in polymer blends containing PP and other polymers such as polyethylene (PE), polystyrene (PS), and ethylene-propylene-diene monomer (EPDM).

The preparation of B2 involves the reactive grafting of maleic anhydride (MAH) onto the polypropylene backbone. This is typically achieved through a melt grafting process, where PP and MAH are melt-blended in the presence of a free radical initiator. The maleic anhydride groups react with the PP backbone to form a grafted copolymer, which has both PP and MAH segments along the polymer chain.

The maleic anhydride functionality on B2 can then react with functional groups on the surface of other polymers in a blend, such as PE or PS, to create a stronger bond between the polymers. This improved compatibility can lead to improved mechanical properties and processing characteristics of the blend.
