  • Patent number: 11859061
    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.
