摘要
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 30 wt. % of polycarpolactone, or a similar ring-opened cyclic ester or ether derivatives. 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.
