Abstract: A process utilizing PET as a reactive constituent to manufacture other polymers containing the pre-condensed moieties by the rapid transesterification of the condensation polymer with a pre-made modifying polymer containing the desired mix of other monomers. The process involves as a first step the manufacture of a modifying polymer containing the desired mix of acids and alcohols to a specific molecular weight such molecular weight dependent on the desired final level of utilized condensation polymer and the finished molecular weight. The second step of the process involves the rapid buildup of molecular weight and/or polymer uniformity by the rapid transesterification of the condensation polymer with the modifying polymer. The second step can be performed in any suitable vessel including an extrusion line. The process has the advantage of greatly reduced cycle times over other condensation polymer utilization processes such as the recycling of PET into other materials.

Abstract: A process for manufacturing block polymer or copolymer from isotactic polypropylene. Polyolefins are introduced into an extruder. Free radical generator is mixed with the polyolefins to form a mixture at room temperature for free radical formation. The mixture is brought up to a temperature of between 175° C. to 220° C. Chain degradation of the polyolefins is induced by the free radical formation to form degraded polymer. Alkenically unsaturated monomers or polymer segments are mixed with the degraded polymer to form a second mixture. The temperature of the second mixture may be lowered to a temperature of between 90° C. to 150° C. The temperature of the second mixture is then adjusted to a temperature between 100° C. to 250° C. to form a novel block polymer or copolymer.
