Claims
- 1. A composite material comprising a fibrous or matted material having added to or impregnated thereon at least one liquid cyclic oligomer of the formula ##STR10## wherein X is selected from the group consisting of alkylene of two to twelve carbon atoms, inclusive, alkylidene of one to twelve carbon atoms, inclusive, cycloalkylene of four to twelve carbon atoms, inclusive, cylcoalkylidene of four to twelve carbon atoms, inclusive, ##STR11## a is zero or 1; n and m are the same or different and are integers of one to about fifteen;
- R is alkylene of two to eight carbon atoms, inclusive or alkylidene of one to eight carbon atoms, inclusive, phenylene or R is a single bond;
- R.sup.1 and R.sup.2 are the same or different and are alkyl or one to four carbon atoms, inclusive or halo;
- b and c are the same or different and are integers of zero to four; and
- R.sub.3 and R.sub.4 are the same or different and are alkyl of one to eight carbon atoms, inclusive, phenyl, hydrogen or R.sub.3 and R.sub.4 are taken together to form an alkylene of two to eight carbon atoms inclusive.
- 2. The composite material of claim 1 wherein the cyclic oligomer has been polymerized in situ and is now high molecular weight aromatic polycarbonate.
- 3. A composite material comprising a fibrous or matted material having added to or impregnated thereon at least one cyclic oligomer of the formula ##STR12## wherein X is selected from the group consisting of alkylene of two to twelve carbon atoms, inclusive, alkylidene of one to twelve carbon atoms, inclusive, cycloalkylene of four to twelve carbon atoms, inclusive, cycloalkylidene of four to twelve carbon atoms, inclusive, ##STR13## a is zero or 1; n and m are the same or different and are integers of one to about fifteen;
- R is alkylene of two to eight carbon atoms, inclusive or alkylidene of one to eight carbon atoms, inclusive, phenylene or R is a single bond;
- R.sup.1 and R.sup.2 are the same or different and are alkyl or one to four carbon atoms, inclusive or halo;
- b and c are the same or different and are integers of zero to four; and
- R.sub.3 and R.sub.4 are the same or different and are alkyl of one to eight carbon atoms, inclusive, phenyl, hydrogen or R.sub.3 and R.sub.4 are taken together to form an alkylene of two to eight carbon atoms inclusive.
- 4. The composite material of claim 3 wherein the cyclic oligomer has been polymerized in situ and is now high molecular weight aromatic polycarbonate.
