摘要: A method comprises forming a reaction mixture comprising a terephthalate polyester, a glycol comprising 2 to 5 carbons, and an amidine organocatalyst; and heating the reaction mixture at a temperature of about 120° C. or more to depolymerize the terephthalate polyester, thereby forming a terephthalate reaction product comprising a monomeric dihydroxy terephthalate diester; wherein the terephthalate reaction product contains terephthalate oligomers in an amount less than the amount of terephthalate oligomers that would result from i) substituting the amidine organocatalyst with an equimolar amount of a guanidine catalyst and ii) depolymerizing the terephthalate polyester under otherwise identical reaction conditions.

摘要: A novel universal main feeder is described for cutting the large items into smaller items before they are fed into the feeder, hopper of the extruder. The sensor based control and the cutting device based resizing and quantity control enables a non-clog and smoother operation for recycling or waste management. The unique design of interchangeable cutting device enables the user to fit the pertinent cutting device blade, knives, shredders or hammer mills.
