Claims24
A copolymer of
- (A) an aliphatic diol bis(allyl carbonate) having the formula ##STR17## where R.sup.1 and R.sup.2 are independently chosen from the groups consisting of hydrogen, Cl, F, Br, and C.sub.1 to C.sub.4 alkyl groups, and R.sub.2 is chosen from the group consisting of alkylene groups, alkylene ether groups, alkylene polyether groups, and alkylene carbonate groups;
- and
- (B) a polyurethane having terminal acrylate functionality.
A liquid composition comprising:
- (A) an aliphatic diol bis(allyl carbonate) having the formula ##STR19## where R.sup.1 and R.sup.2 are independently chosen from the groups consisting of hydrogen, Cl, F, Br, and C.sub.1 to C.sub.4 alkyl groups, and R.sub.2 is chosen from the group consisting of alkylene groups, alkylene ether groups, alkylene polyether groups, and alkylene carbonate groups;
- and
- (B) a polyurethane having terminal acrylate functionality.
A method of increasing the impact strength of diol bis(allyl carbonate) polymerizates comprising adding an effective amount of a polyurethane having terminal acrylate functionality to the diol bis(allyl carbonate), and thereafter polymerizing the resulting composition.
A copolymer of a polyol (allyl carbonate) and a polyurethane having terminal acrylate functionality.
A liquid composition comprising a polyol (allyl carbonate) and a polyurethane having terminal acrylate functionality.
A method of increasing the impact strength of a polyol(allyl carbonate) comprising adding an effective amount of a polyurethane having terminal acrylate functionality to the monomeric polyol (allyl carbonate) and thereafter polymerizing the resulting composition.
