PMMA PASTE

摘要

A PMMA paste comprising a mixture of A methyl methacrylate that has a methacrylic acid content of less than 1% and a water content of less than 1% and B at least one polymethyl methacrylate that has a Tg of more than 65°C and a molar mass of greater than or equal to 200 000 g/mol, the methyl methacrylate fraction being sufficient for the PMMA paste to be autosterile, and the weight ratio of B to A being 10-50% B to 50-90% A, can be used to produce paste-like one-component bone cements and two-component bone cements.
