Impact of Graft Ratio on the Properties of Maleic Anhydride Grafted Polyethylene
The performance of maleic anhydride grafted polyethylene (MAPE) is strongly influenced on the graft ratio, which represents the amount of grafted maleic anhydride units per polyethylene chain. A higher graft ratio typically leads to boosted adhesion properties due to the greater number of polar maleic anhydride groups available for bonding with other materials. Moreover, a greater graft ratio can cause modifications in the physical properties of MAPE, such as ductility, depending on the specific application and processing conditions.
Conversely, excessively high graft ratios can impair the overall compatibility of the here material, necessitating careful optimization of the graft ratio to achieve the desired properties for a particular application.
