Abstract
The invention relates to laminates of polyhydantoins.
Claims18
A laminate comprising polyhydantoins of units attached head-to-tail corresponding to ##STR5## where R.sup.1 and R.sup.2 are independently a C.sub.2 -C.sub.20 -alkylene radical, a C.sub.2 -C.sub.20 -alkylene radical substituted with halogen, a C.sub.2 -C.sub.20 -alkylene radical substituted with C.sub.1 -C.sub.10 -alkyl groups, or combinations thereof, a C.sub.6 -C.sub.14 -arylene radical, a C.sub.5 -C.sub.12 -cycloalkylene radical, or a C.sub.7 -C.sub.20 -aralkylene radical,
- R.sup.3 is hydrogen, R.sup.4 is a radical --CH.sub.2 --COR.sup.5, in which R.sup.5 is an amino group, a C.sub.1 -C.sub.10 -alkylamino, a C.sub.1 -C.sub.10 -dialkylamino, a C.sub.1 -C.sub.10 -alkoxy or a C.sub.6 -C.sub.10 -aroxy group and
- a fibrous filler or reinforcing material.
A process for producing a laminate of polyhydantoins of units attached head-to-tail corresponding to ##STR6## where R.sup.1 and R.sup.2 are independently a C.sub.2 -C.sub.20 -alkylene radical, a C.sub.2 -C.sub.20 -alkylene radical substituted with halogen, a C.sub.2 -C.sub.20 -alkylene radical substituted with C.sub.1 -C.sub.10 -alkyl groups, or combinations thereof, a C.sub.6 -C.sub.14 -arylene radical, a C.sub.5 -C.sub.12 -cycloalkylene radical, or a C.sub.7 -C.sub.20 -aralkylene radical,
- R.sup.3 is hydrogen, R.sup.4 is a radical --CH.sub.2 COR.sup.5, in which R.sup.5 is an amino group, a C.sub.1 -C.sub.10 -alkylamino, a C.sub.1 -C.sub.10 -dialkylamino, a C.sub.1 -C.sub.10 -alkoxy or a C.sub.6 -C.sub.10 -aroxy group and
- a fibrous filler or reinforcing material, comprising combining the polyhydantoins with the fibrous filler or reinforcing material to form a mass, then compressing and hardening the mass at elevated temperatures to form the laminate.
