titleOfInvention | Process for preparing high impact monovinylaromatic polymers in the presence of a borane complex |
abstract | The present invention relates to a process for preparing a high impact monovinylaromatic polymer comprising admixing a rubber, at least one monovinylaromatic monomer and optionally one or more comonomer in the presence of at least a borane complex of the L-BH3 type wherein L is a Lewis base and polymerizing the monovinylaromatic monomer. The borane complex initiator, L may be an ether (e.g THF, tetrahydrofurane), a thioether (e.g dimethylthioether) or an amine. A preferred complex is an amine borane such as by way of example triethylamine borane. The present invention also relates to a high impact monovinylaromatic polymer having a weight ratio of grafted monovinylaromatic monomer and optional comonomer to the initial monovinylaromatic monomer and optional comonomer above 0.1 %, advantageously above 2% and preferably in the range 2 to 4 %. The invention is of particular interest to make high impact polystyrene. |
