Abstract
Abstract An improved nonflammable coating composition containing vinyl chloride, dialkyl maleate, and bis (2-chloroethyl) vinyl phosphonate, the improvement comprising forming a tertelomer using a free radical initiator in the presence of xylene, wherein the alkyl constituent of the maleate contains from 3 to 15 carbon atoms and the alkyl constituent of the phosphonate contains from 1 to 15 carbon atoms.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
136 words
An improved, nonflammable coating composition containing vinyl chloride, dialkyl maleates, and bis-2-chloro alkyl vinyl phosphonates, the improvement comprising forming a tertelomer using a free radical initiator in the presence of at least, based on one mole of vinyl chloride, 0.25 moles of xylene, and from about 0.01 to 1 moles vinyl phosphonate and 0.05 to 0.5 moles of dialkyl maleate, wherein the maleate is defined by: ##STR3## and wherein the phosphonate is defined by: ##STR4## wherein R and R 1 are the same or different alkyl radicals containing from 3 to 15 carbon atoms, R 2 and R 3 are the same or different alkyl radicals containing from 1 to 15 carbon atoms and x is selected from the group consisting of hydrogen, halogens, and alkyls, cyanoalkyls and haloalkyls containing from 1 to 18 carbon atoms.
Claim 2
Dependent Claim
136 words
An improved, nonflammable coating composition containing vinyl chloride, dialkyl maleates, and bis-2-chloro alkyl vinyl phosphonates, the improvement comprising forming a tertelomer using a free radical initiator in the presence of at least, based on one mole of vinyl chloride, 0.25 moles of xylene, and from about 0.01 to 1 moles vinyl phosphonate and 0.05 to 0.5 moles of dialkyl maleate, wherein the maleate is defined by: ##STR3## and wherein the phosphonate is defined by: ##STR4## wherein R and R 1 are the same or different alkyl radicals containing from 3 to 15 carbon atoms, R 2 and R 3 are the same or different alkyl radicals containing from 1 to 15 carbon atoms and x is selected from the group consisting of hydrogen, halogens, and alkyls, cyanoalkyls and haloalkyls containing from 1 to 18 carbon atoms.
Claim 3
Dependent Claim
38 words
A telomeric coating composition as described in claim 1, wherein the free radical initiator is selected from the group consisting of benzoyl peroxide, lauryl peroxide, 2,4 dichlorobenzoyl peroxide, azobisisobutylnitrile, p-chlorobenzoyl peroxide, t-butyl peracetate, t-butyl perbenzoate, and t-butyl hydroperoxide.
Claim 4
Dependent Claim
32 words
A composition as described in claim 1, wherein the dialkyl maleates are selected from the group consisting of di-n-butyl maleate, di-isobutyl maleate, di-n-hexyl maleate, di-n-octyl maleate, di-n-decyl maleate, and mixtures of these.
Claim 5
Dependent Claim
34 words
A composition as described in claim 1 when prepared at a reaction temperature of from about 25° to about 100° C. for a period of time of from about 2 to about 24 hours.
