Compound compatible with inorganic solids, and with homopolymers and copolymers of propylene and of ethylene

Abstract

Disclosed is a compound comprising a saturated oligomer of isoprene bonded to a polar group, said compound having formula (I): in which R is H or a C1-C4 alkyl, n is 2-17, and R′ is a radical selected from the group consisting of X, COOR″, CN, NR2, and NR2.HX, wherein R″ is selected from the group consisting of R, NR2, and NR2.HX or a monovalent metal cation, X being I, Cl, Br or F, and each R in NR2 and NR2.HX being the same or different. In a preferred embodiment the polar group is a quaternary ammonium radical. The compound is useful as a compatibilizer of solid inorganic material, and propylene and ethylene polymer material.
