摘要
Various fabrication properties of polyvinyl chloride are improved such as melt flow by treating the polyvinyl chloride resin with a low inherent viscosity-high glass transition temperature enhancing agent. The treatment occurs as a suspension or mass overpolymerization on the polyvinyl chloride resin by reacting at least one high glass transition temperature enhancing agent with at least one chain transfer agent. The formed high glass transition temperature-low inherent viscosity agent imparts a high glass transition temperature to the polyvinyl chloride resin and also reduces the inherent viscosity to a level below the inherent viscosity formed by the combined effect of the polyvinyl chloride resin and the glass transition temperature agent.
