Abstract
Official abstract text for this publication.
Disclosed is a method for improving vibration damping of a substrate, such as the underbody of an automobile. The method comprises applying a plastisol which comprises a polymeric component and a plasticizer. The fused plastisol has improved damping behavior as determined using Dynamic Mechanical Thermal Analysis. Novel plastisols and novel plasticizers are also disclosed.
First claim
Opening claim text (preview).
We claim: 1. A plasticizer comprising the esterification product formed by the reaction of formula (I) R 1 COOH (I) and formula (II) R 2 COOH (II) or the corresponding esters, anhydrides, and/or acid chlorides of formula (I) and/or formula (II), with formula (III) and formula (IV) wherein R 1 and R 2 are independently selected from the group consisting of phenyl, tolyl, cyclohexyl, 1-ethylpentyl, and methyl. 2. The plasticizer according to claim 1 , wherein R 1 is phenyl and R 2 is methyl. 3. The plasticizer according to claim 1 , wherein the ratio of phenyl to tolyl ranges from 0.05:20 to 20:0.05 based on the total amount of said esterification product. 4. The plasticizer according to claim 1 , wherein R 1 and R 2 are the same. 5. The plasticizer according to claim 1 , wherein said plasticizer comprises said esterification product formula (V) and formula (VI) and wherein said esterification product comprises at least 10 weight percent of a mixed ester, based on the total weight of said esterification product.
