✦ 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.

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

## Abstract The composition dependence of the Raman spectra of the mixed ion vermiculites [(CH~3~)~4~N^+^]~1‐__x__~ [(CH~3~)~3~NH^+^]~__x__~‐V (V = vermiculite) have been studied in the range 0 ⩽ __x__ ⩽ 1. The torsional mode frequencies exhibit a small shift (__ca.__ 2 cm^−1^) to lower energy with
