| List-I | List II | ||
|---|---|---|---|
| A. | Phenol-formaldehyde resin | I | Glyptal |
| B. | The copolymer of 1,3-butadiene and styrene | II | Novolac |
| C. | Polyester of glycol and phthalic acid | III | Buna-S |
| D. | Polyester of glycol and terephthalic acid | IV | Dacron |
To solve this matching question, we need to understand the properties and common applications of each type of polymer mentioned. Let's match List-I with List-II using our knowledge of these substances:
Based on the matches above, the correct option is: A-II, B-III, C-I, D-IV.


If a random variable \( x \) has the probability distribution 
then \( P(3<x \leq 6) \) is equal to
Neoprene is formed from chloroprene. It is prepared by free radical polymerisation. The monomer of neoprene is chloroprene. It is used for preparing gaskets, conveyor belts etc.
