Abstract

"USO DE INICIADORES TETRAFUNCIONAIS PARA APERFEIçOAR O VOLUME DE FASE DE BORRACHA DE HIPS". A presente invenção refere-se a produtos de poliestireno, tal como poliestireno de alto impacto (HIPS), que podem ser obtidos por polimerização de estireno com um polímero de dieno na presença de pelo menos um iniciador multifuncional. A presença do iniciador multifuncional tende a causar estruturas mais ramificadas no poliestireno. Inesperadamente, a razão de % de gel para % de borracha (G/R ou volume de fase de borracha) aumenta quando o índice de intumescimento aumenta que é o oposto da tendência convencional. Adicionalmente, valores de G/R aceitáveis podem ser alcançados a razões de polimerização aumentadas com estes iniciadores."USE OF TETRACTIONAL INITIATORS TO IMPROVE THE HIPS RUBBER PHASE VOLUME". The present invention relates to polystyrene products, such as high impact polystyrene (HIPS), which may be obtained by styrene polymerization with a diene polymer in the presence of at least one multifunctional initiator. The presence of the multifunctional primer tends to cause more branched polystyrene structures. Unexpectedly, the ratio of% gel to% rubber (G / R or rubber phase volume) increases as the swelling rate increases which is the opposite of the conventional trend. Additionally, acceptable G / R values can be achieved at increased polymerization ratios with these primers.
