  • Patent number: 4000100
    Abstract: This invention comprises the polyvinyl chloride stabilizer composition of an unactivated Zeolite A molecular sieve or an unactivated naturally occurring molecular sieve of essentially the same pore size range as Zeolite A and a conventional inorganic, organometallic or organic stabilizer, or mixture of these stabilizers.
