This copolymer contains 80 mol% succinate and 20 mol% adipate
(10); the weight-average and number-average molecular weights are 165,000 g/mol and 62,000 g/ mol, respectively (11).
Schimmenti, director of marketing, Intermediates, emphasizes the company's integrated raw material strengths and the industry's most extensive product slate of phthalate, adipate
, and trimellitate plasticizers.
A newly launched line of colorants and additives was developed specifically for use in biodegradable polymers such as polylactide (PLA), polyhydroxybutyratevalerate copolymer (PHBV), polybutene succinate (PBS), polybutylene adipate
co-terephthalate (PBAT), and starch blends.
Examples include Di-(butoxyethoxy) phthalate, Di-(butoxyethoxy) adipate
, and Di-(butoxyethoxy) sebacate.
Compared with pure PHB, they found a decrease of the Young's modulus in all of the blends under investigation, and concluded that blending with natural starch and starch adipate
resulted in more brittle materials.
Plasticizers such as dibutoxyethyl adipate
(DBEA) and dibutoxyethoxyethyl adipate
(DBEEA) are examples of ester plasticizers that fall under these regulations.
Di-PPG-2 Myreth-10 Adipate
 is an extremely mild emollient ester, providing exceptional skin feel, while also reducing irritation of surfactant systems.
The higher polarity of the dioctyl adipate
is overshadowed by its low molecular weight.
Currently, a recognized leader in the area of dynamic polyurethane elastomer performance is the Vulkollan elastomer system, a product of Bayer, which is prepared by the reaction of naphthalene diisocyanate (NDI) with one of several adipate
ester polyols to produce a prepolymer which can then be chain extended with short chain diols such as butane diol (figure 1).
In all 19 oils were assessed: castor oil, PPG-15 stearyl ether, propylene glycol isostearate, isostearyl isostearate, isostearyl alcohol, triisostearin, trimethylolpropane triisostearate, polyglyceryl-3 diisostearate, ethylhexyl cocoate, ethylhexyl pelargonate, pentaerythrityl tetracaprylate/caprate, PPG-3 benzyl ether myristate, isotridecyl isononanoate, di-PPG-2 myreth-10 adipate
, PCA dimethicone, pentaerythrityl isostearate/caprate/caprylate/adipate
, PPG-3 hydrogenated castor oil, di-PPG-3 myristyl ether adipate
A large number of studies deals with association of native starch, or modified starch, with a biopolymer such as poly([epsilon]-caprolactone) (PCL), poly(lactic acid) (PLA), poly(hydroxyalcanoate) (PHA), poly(butylene adipate
terephthalate) (PBAT) (17-23).
