Latest Patents
Bertrand's latest patents focus on innovative compositions of high impact polystyrene. The first patent describes a composition obtained by mixing polystyrene with a master-batch composition that includes a mixture of a vinyl aromatic polymer, a rubbery dienic polymer, and a sequenced copolymer of styrene and diene. The total styrene polymer content in this master-batch composition is between 50 and 80% by weight, while the total rubber content ranges from 20 to 50% by weight. The sequenced copolymer content is designed to introduce from 3 to 90% by weight of the total rubber in the composition.
The second patent also pertains to high impact polystyrene composition, comprising a mixture of a styrene polymer, a rubbery dienic polymer, and a sequenced copolymer of styrene and diene. In this composition, the total styrene polymer content is between 50 and 99% by weight, and the total rubber content is between 1 and 50% by weight. The amount of sequenced copolymer is such that it contributes from 3 to 90% by weight of the total rubber in the composition.
