  • Patent number: 6765058
    Abstract: A crosslinkable composition of a polymeric thermoplastic and/or elastomeric material which is susceptible to scorching when processed at elevated temperatures, prior to crosslinking, in the presence of a free radical initiator, is protected against such scorching by the incorporation therein of a mixture of at least one hydroquinone compound and a sulfur accelerator. This mixture may also contain at least one monomeric allylic, methacrylic, acrylic or diene type coagent. The mixture exhibits a synergistic effect resulting in improved scorch protection for peroxide cured systems when compared with the protection afforded by the components singly.

  • Patent number: 6734230
    Abstract: A procedure for the production of a modified acrylic sheet with high impact resistance, of the type in which a prepolymerization is done of a mix of monomers with a polymer of dissolved dienic monomers. The procedure is done in batches at low temperatures without there being a separation of the polymer of dienic monomers from the rest of the mix. The procedure facilitates obtaining a modified acrylic sheet with high impact resistance whose transmittance is kept after being subjected to an accelerated degradation, and whose impact properties are not reduced more than 50% after said accelerated degradation.
