ABSTRACT:
This invention is a thermoplastic saturated polyester low profile additive (low profile additive) useful in sheet molding compounds for parts, especially vehicle parts, the additive has a major component derived from aromatic compounds such as terephthalic acid including recycled polyethylene terephthalate. Asymmetrical glycols are an important ingredient and can be used to digest recycled PET to make oligomeric glycols which are reacted with acids having fewer than 12 carbon atoms to make one of the low profile additives of this invention.
