Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
72 words
A COMPOSITION RESISTANT TO THE DETERIORATING EFFECTS OF HEAT AND LIGHT COMPRISING A CHLORINE-CONTAINING RESIN POLYMER DERIVED FROM AN UNSATURATED MONOMER AND AS A STABILIZER THEREFOR A TRIALKYLTIN PROPIOLATE HAVING FROM 1 TO 18 CARBON ATOMS IN EACH ALKYL GROUP BONDED TO THE TIN ATOM OF THE MOLECULE IN HEAT AND LIGHT STABILIZING AMOUNTS OF FROM 0.1 TO 10 PARTS BY WEIGHT PER 100 PARTS BY WEIGHT OF THE CHLORINE-CONTAINING RESIN POLYMER.
Claim 2
Dependent Claim
72 words
A COMPOSITION RESISTANT TO THE DETERIORATING EFFECTS OF HEAT AND LIGHT COMPRISING A CHLORINE-CONTAINING RESIN POLYMER DERIVED FROM AN UNSATURATED MONOMER AND AS A STABILIZER THEREFOR A TRIALKYLTIN PROPIOLATE HAVING FROM 1 TO 18 CARBON ATOMS IN EACH ALKYL GROUP BONDED TO THE TIN ATOM OF THE MOLECULE IN HEAT AND LIGHT STABILIZING AMOUNTS OF FROM 0.1 TO 10 PARTS BY WEIGHT PER 100 PARTS BY WEIGHT OF THE CHLORINE-CONTAINING RESIN POLYMER.
Claim 3
Dependent Claim
128 words
