Polypropylene-clay hybrids (PPCH) were prepared using a maleic anhydride-modified PP oligomer (PP-MA) as a compatibilizer. PP was melt-blended with organophilic clay which was intercalated with PP-MA. In these PPCHs, the particles of silicate layers were dispersed at the nanometer level. The particl

✦ Synopsis
The synthesis of polypropylene (PP) oligomer-clay intercalation compounds was studied by using three kinds of PP oligomers and organophylic clay. PP oligomers were two types of maleic-anhydride-modified PP oligomers containing different amount of maleic anhydride groups and one type of hydroxy modified PP oligomer. Organophylic clay was sodium-ion-exchanged montmorillonite with octadecylammonium ion (C18-Mt). PP oligomer was mixed with C18-Mt at 200ЊC. Maleic-anhydridemodified PP oligomer, which was of high acid value type, and hydroxy-modified PP oligomer were intercalated between silicate layers of clay; and PP oligomer-clay intercalation compounds were synthesized successfully. But maleic-anhydride-modified PP oligomer, which was of low acid value type, was not intercalated.
