[EN] The present invention discloses cyclopentane carboxylate compounds. The I-hydrocarbyl-2-acyloxy-cyclopentane carboxylates according to the invention have a general formula (I): wherein groups R1, R2 and R3, which are identical or different, are independently selected from the group consisting of linear or branched C1-C20alkyl, C3-C20cycloalkyl, C6-C20aryl, C7-C20alkaryl and C7-C20aralkyl. The present invention also discloses a process as well as intermediate compounds for preparing the compounds of formula (I), and use of the compounds (I) as electron donor in the preparation of catalysts for propylene polymerization.

The present invention is related to the field of colloid chemistry and to other fields were there is a need to reduce interfacial tension, including such application at lowered or elevated temperatures. In particular present invention is related to chemically-stable surfactants bearing cyclopentane moiety(ies) incorporated into a hydrophobic chain, said surface active agents being described by general formula (I) wherein: R1 is a polar group; T is a -(CH2)z-CH3 or -(CH2)Z-R2; R2 is a polar group the same as or different from R1; m, n, k, p, and z are integers from 0 up to 40; a, b, and c are 0 or 1 independently of each other. Such surfactants show broad working temperature range, and applicability in aggressive environments without deterioration of environmental safety.
