Beschreibung
Zusammenfassung:	Improved molding composition comprising (1) polyvinyl chloride, which is blended with a dehydrochlorinating agent such as a stannous salt; (2) a free-radically polymerizable monomer and/or macromer, wherein the monomer contains at least one terminal CH2=C< group per molecule and the macromer contains at least one double bond in the polymeric backbone; (3) an ionically polymerizable monomer and/or macromer containing the oxirane group with an optional curing agent; (4) a heterofunctional monomer containing at least one oxirane group and at least one CH2=C< group per molecule; and (5) a free radical initiator results in an improvement in thermo-mechanical properties.
