All the tools & learning materials you need for study success - in one app.
Get started for freeDraw the structure of PEF, polyethylene furanoate, a condensation polymer formed from furandicarboxylic acid and ethylene glycol. PEF, which can be synthesized from precursors that are obtained from renewable resources, has many of the same properties as polyethylene terephthalate (PET).
Draw the structure of the three monomers used to prepare polybutyrateadipate terephthalate (PBAT), a biodegradable copolymer sold under the trade name of Ecoflex. Because PBAT has properties similar to low-density polyethylene, it can be used in biodegradable food packaging and plastic bags.
PBAT
Melmac, a thermosetting polymer formed from melamine and formaldehyde , is used to make dishes and countertops. Draw a stepwise mechanism for the condensation of one mole of formaldehyde with two moles of melamine, which begins the synthesis of Melmac.
The reaction of p-cresol with ensembles the reaction of phenol (PhOH) with , except that the resulting polymer is thermoplastic but not thermosetting. Draw the structure of the polymer formed, and explain why the properties of these two polymers are so different.
ABS, a widely produced copolymer used in crash helmets, small appliances, and toys, is formed from three monomers- acrylonitrile , buta-1,3-diene , and styrene (CH2 =CHPh). draw a possible structure for ABS.
