Abstract
Some poly(vinyl chloride) containing allyl group at different degrees were prepared by the coupling reaction between poly(vinyl chloride) and allylmagnesium chloride in tetrahydrofuran. The polymers obtained were crosslinked by using peroxide at 140°C
The measurements of physical properties of the modified polymers lead to the following results:
The insoluble portion of the polymer in tetrahydrofuran increased with an increase in the time of molding and the unsaturation cantent. The mechanical properties suchas tensile strength, 100%-modulus and hardness became poor with an increase in the unsaturation content. With an increasing unsaturation content, the valve of elongation decreased for non-crosslinked polymer, but increased for crosslinked polymer.
