description A presente invenção refere-se a compostos de metaloceno de háfnio tendo um grupo substituído na posição 3 de pelo menos um anel ciclopentadienila representado pela fórmula -R20-SiR'3 ou -R20-CR'3, em que R20 é uma hidrocarbila C1 a C4 e R? é uma hidrocarbila C1 a C20 substituída ou não substituída. This invention relates to hafnium metallocene compounds having a group substituted at the 3 position of at least one cyclopentadienyl ring represented by the formula -R20-SiR'3 or -R20-CR'3 where R20is a C1 to C4 hydrocarbyl and R' is a C1 to C20 substituted or unsubstituted hydrocarbyl.
