Matrix materials and a process for their preparation |
| abstract |
Polyurethane-based matrix materials are made by reacting a phenol which is at least bifunctional with an aromatic isocyanate which is at least difunctional in the presence of 1-40 wt. % soft segment former. The soft segment former is a compound containing long chain aliphatic groups having at least six carbon atoms in the aliphatic group, an isocyanate-reactive group and a molecular weight of from 800 to 10,000. From 90 to 130 equivalent percent of isocyanate groups (based on the total of isocyanate-reactive groups present in the phenol and soft segment former) are employed. These matrix materials are particularly useful in the production of composite materials and as adhesives. |
