摘要： Improved stabilizer compositions are provided which impart significant long-term stabilization to halogen containing polymers such as polyvinyl chloride. The improved stabilizer compositions incorporate an alkali-metal hydrogen phosphate compound, such as anhydrous disodium hydrogen phosphate, of a predetermined surface area. The novel inorganic phosphate enables a reduction in the amount of organmetallic stabilizer, if desired, while still yielding long-term stability in the resultant polymer, or the ability to raise process temperature and reduce cycle times of molding operations.

摘要： Methods are provided for abrading dyed fabric to produce a stonewashed effect by tumbling the fabric with stones of a chemical composition that is soluble in wash or rinse liquid for the fabric, where the stones are of sufficient size and hardness to effect abrasion of the fabric without substantial mechanical disintegration of the stones and in a manner simulating the action of pumice stone. The chemical stonewashing composition may be a compacted powder, agglomerate, coagulate, or other integral mass or solid formed from an alkali or alkaline earth metal carbonate, bicarbonate, silicate, sulfate, borate, halide, hydroxide or hydrate or peroxyhydrate thereof, for example.
