Grafting, degree

Maleation of iPP was carried out in a high-pressure vessel. After a desired time interval, the vessel was quenched with running cold water to terminate the reaction. Samples were taken out and then purified for subsequent determination of the grafting degree [5]. 

PMHS-CD with 10, 20 and 30% grafting degrees were synthesized in the same way using the suitable stoichiometric amount of monoaUyl p-cyclodextrin. 

Grafting Degree. The variation in degree of grafting was correlated with the 1,2-vinyl content of PB, the monomer concentration (effect of preferential solvation by the monomer), the type and the concentration of initiator (preferential solvation by initiators), and the degree of conversion. The effect of the structure of PB on the grafting degree is tabulated in Table V. 

A suspension of PE-gr-poly(acrylic) acid (grafted degree 5.0 wt.%) in ethanol was put into a temperature-controlled glass reactor at 50 °C. A solution of Cu(OCOCH3)2 in ethanol was added to the suspension and stirred for 1 h. Then the suspension was filtered, washed with ethanol and dried. The product obtained was reduced by NaBH4. The content of Cu and the size of nanoparticles formed were analysed. 

Again, these equilibria may be, at least in part, responsible for the increased grafting degree in the presence of AcCL.
