Claims (13)

An effective amount of a mixture comprising at least one anti-combustion agent and at least one bicyclic phosphate compound of the following structural formula, and a smoke suppressing thermoplastic resin composition comprising polyvinyl halide, polyolefin or polystyrene resin. Wherein X is OH, OR 'or OC (O) R'; R is H or saturated unsaturated straight or branched C ₁ -C ₁₇ alkyl; R 'is saturated or unsaturated straight or branched C ₁ -C ₁₇ alkyl. The composition according to claim 1, wherein the combustion inhibitor is selected from the group consisting of halogenated compounds, metal hydrates, metal borates, antimony compounds, phosphorus compounds and mixtures thereof. The method of claim 1 wherein the anti-burning agent is selected from the group consisting of di- (2-ethylhexyl) tetrabromophthalate, alumina trihydrate, magnesium hydroxide, antimonitrioxide, zinc borate and alkaryl phosphate A composition, characterized in that losing. The compound according to claim 1, wherein the bicyclic phosphate compound is selected from 2,6,7-trioxa-phosphobicyclo [2,2,2] -octane-4-methanol-1-oxide; Or 2,6,7-trioxa-1-phosphobiscyclo [2,2,2] -octane-4-methanol, acetate, 1-oxide. The composition of claim 1 wherein the resin is selected from the group consisting of single and copolymers of polyvinylchloride, polystyrene and polyethylene, polypropylene and polybutylene. The composition according to claim 4, wherein the bicyclic phosphate compound is polyvinyl chloride. The composition according to claim 1, wherein the weight ratio of the bicyclic phosphate compound to the combustion inhibitor is in the range of 1:25 to 20: 1. The composition of claim 1, wherein the mixture of the bicyclic phosphate compound and the flame retardant is given at a level in the range of about 2 to 50 percent by weight of the total resin composition. A method for suppressing the smoke-producing properties of a polyvinyl halide, polyolefin or polystyrene resin composition during combustion, comprising the step of comprising an effective amount of a mixture comprising a combustion inhibitor and a bicyclic phosphate compound of the structure: Wherein X is OH, OR 'or OC (O) R'; R is H or saturated or unsaturated straight or branched C ₁ -C ₁₇ alkyl. 10. The composition of claim 9, wherein the anti-combustion agent is selected from the group consisting of halogen compounds, metal hydrates, metal borates, antimony compounds, phosphorus compounds and mixtures thereof. 10. The method of claim 9 wherein the burnout agent is selected from the group consisting of di- (2-ethylhexyl) tetrabromophthalate, alumina trihydrate, magnesium hydroxide, antimonitrioxide, zinc borate and alkaryl phosphate A composition, characterized in that losing. The bicyclic phosphate compound according to claim 9, wherein the bicyclic phosphate compound is 2,6,7-trioxa-phosphobiscyclo [2,2,2] -octane-4-methanol-1-oxide or 2,6,7-trioxa- 1-phosphobicyclo [2,2,2] -octane-4-methanol, acetate, 1-oxide. 10. The method of claim 9, wherein the weight ratio of bicyclic phosphate to combustion inhibitor is in the range of 1:25 to 20: 1. ※ Note: The disclosure is based on the initial application.
