摘要:
Disclosed herein is a method for improving the physical properties of cellulose fiber-containing material/PVC composites comprising adding to said composites an effective amount of at least one compatibilizer comprising an organometallic zirconium compound. The preferred organometallic zirconium compound is cyclo[dineopentyl(diallyl)]pyrophosphato dineopentyl(diallyl)zirconate. Articles of manufacture comprising such composites are also disclosed.
摘要:
Disclosed herein is a process for improving mechanical and chemical properties of a composite of poly(vinyl chloride) and at least one natural fiber comprising adding to said composite at least one heat stabilizer selected from the group consisting of: A) alkyltin reverse esters-sulfides; B) alkyltin alkyl maleates; and C) complex mixtures of calcium and/or zinc carboxylates/acetylacetonates.
摘要:
A process for production of a t-alkyl peroxide compound includes the steps of: a) reacting an n-alkyl t-alkyl ether with a reactant mixture comprising an acid catalyst and a compound of the formula RO2H (I) where R is H or t-alkyl, provided that if R is t-alkyl the t-alkyl peroxide compound product is a di-t-alkyl peroxide, and b) isolating a reaction product comprising said t-alkyl peroxide compound from the mixture resulting from step a). The process can be used to prepare t-butyl hydroperoxide or di-t-butyl peroxide from methyl t-butyl ether. Sulfuric acid may be used as the acid catalyst.
