Question

ABS, a widely produced copolymer used in crash helmets, small appliances, and toys, is formed from three monomers- acrylonitrile $\left({\mathrm{CH}}_2=\mathrm{CHC}\equiv N\right)$, buta-1,3-diene $\left({\mathrm{CH}}_2=\mathrm{CH}-\mathrm{CH}={\mathrm{CH}}_2\right)$ , and styrene (CH₂ =CHPh). draw a possible structure for ABS.

Short answer

Answer

Step-by-step solution

ABS

ABS polymer also termed as ‘acrylonitrile butadiene styrene’ comes under the category of thermoplastic polymer. It can withstand several acids, alkalis, and vegetable & mineral oils. When subjected to elevated temperatures, it catches fire.

Monomers

Monomers possess a vital role in living organisms. They are the units of several biomolecules like DNA, RNA, and carbohydrates. Glucose that come under natural monomers is important for numerous bodily functions.

Predicting the possible structure for ABS from the monomers acrylonitrile, buta-1,3-diene, and styrene

The monomers of ABS acrylonitrile, buta-1,3-diene, and styrene can be given as:

Monomers of ABS

The monomersacrylonitrile, buta-1,3-diene, and styrene join in varying amounts to generate the copolymer ABS. The structure of ABS can be given as:
