Abstract: A concentrate carrier system for adding colorants and/or other additives to resin formulations over a broad range of processing temperatures is described. The carrier system includes at least 20 wt. % of a base acrylate copolymer, such as ethyl-methyl acrylate, provided in combination with less than 55 or less than 30 wt. % of a ring-opened cyclic ester or ether derivative, such as polycaprolactone, polyhydroxyalkonates, polyglycolide, polylactide, poly(butylene succinate), other aliphatic linear polyesters. The remainder, which may include an optional organic plasticizer such as epoxidized soybean oil, is dedicated to an additive package that may include colorants, property enhancers, and/or non-property fillers.

Abstract: A highly loaded and well-dispersed masterbatch composition and process for making thereof from a split stream process. The masterbatch composition includes a colorant, a thermoplastic carrier, a metallocene polymer processing aid, and optionally an additive. The split stream may be formed of a primary feed and a secondary feed. The primary and second feeds are combined by at least one of the following: supplying the secondary feed in either the same feed port as the primary feed, in a stream located upstream the primary feed, in a stream located downstream the primary feed, or a combination thereof.
