1. A solid catalyst component for use in olefinic polymerization, comprising:
titanium compound, magnesium compound, halogen, and a combination of internal electron donor compounds, wherein said combination of internal electron donor compounds comprises at least one 1,8-naphthyl diester compound represented by general formula (I): wherein R1 and R2 are each independently selected from the group consisting of a hydrogen; a halogen; and a linear or branched, cyclic or acyclic, saturated or non-saturated C1 to C22 hydrocarbyl group, wherein the hydrocarbyl group optionally contains a —O—, —NH—, or —S— group in place of a —CH2— group or a —N═ group in place of a —C═ group, and wherein the hydrocarbyl group is optionally substituted by one or more halogens, and wherein R3, R4, R5, R6, R7, and R8 are each independently selected from the group consisting of a hydrogen; a halogen; and a linear or branched, cyclic or acyclic, saturated or non-saturated C1 to C22 hydrocarbyl group, wherein the hydrocarbyl group optionally contains a —O—, —NH—, or —S— group in place of a —CH2— group or a —N═ group in place of a —C═ group, and wherein the hydrocarbyl group is optionally substituted by one or more halogens; and at least one secondary internal donor compound selected from the group consisting of mono- or poly-carboxylic esters, ethers, ketones, organic compounds containing carboxylic and ether groups, organic compounds containing carboxylic groups and carbonyl groups, and organic compounds containing carboxylic groups, ether groups, and carbonyl groups. |
