  1. Sachin Korde

    From where I can get books for GATE 2021, and what publication or author should I choose ?

  2. shama firdaus

    i am student of msc polymer science and technology of amu aligarh, sir i want to ask if i am eligible for mtech polymer science and engineering after qualifying gate exam and for the phd program

  3. Sandhili

    I am a btech in textile chemistry. I want to pursue mtech in polymer chemistry. From which branch should i apply for gate ?

  4. shubh chaudhary

    i m diplomat in plastics engg so is polymer engg or paint technology is more preferable in higher edu.


    myself Brajyadav, i have completed chemistry can i do in polymer .please reply

    1. SRUTHI M

      Yes you can

  6. leena

    I am a BE chemical from Mumbai University .i want to do Mtech in Polymer science and engineering.
    So will it be easy to crack a GATE for me as i am a chemical engineer?

    1. SRUTHI M

      Sure it will be easy for you to crack if you are covering entire syllabus of polymer

  7. ashish

    sir! if i doing in polymer sciences then can i eligible for giving GATE exam?
    which branch is more demandable polymer sc. or instrumentation?

  8. Ulkesh Jadhav

    Sir i am third year B.TECH student. i am studying PAINT technology at I.C.T Mumbai. i want to prepare for gate exam so which books i have to refer and coaching classes are must or not

  9. nalin

    go for M-Tech Chemical or petrochemical engineering, dont try polymer tech there is only little scope.

  10. sai r

    Sir ,can you please suggest the institutes for polymer engineering gate preparation.A quick reply will be appreciated as I really need your worthy suggestion.

  11. Priyanka

    I did diploma in plastic and now doing B.Tech in chemical. But still i have interest in plastic engg. As per scope concern which branch will better for M.Tech. please suggest me.

  12. suresh

    To Mukesh and Jignesh,
    You can get an M.Sc. in Polymer Science, not M.Tech. M.Tech will be in Polymer Engineering not Science. Polymer Science and Polymer Engineering are two different majors. The relation between Polymer Science and Polymer Engineering is similar to Physics and Electronics Engineering. Physics gives the basics for Electronics Engineering. But Electronics is not Physics!

    Typically, an ‘M.Sc. in Polymer Science’ and ‘M.Tech in Polymer Engineering’ will not have even one subject in common when it comes to their respective syllabus.
    M.Tech admission in most colleges is given based on your ‘GATE exam’ score.

  13. jignesh patel

    iam surface coating technology student so plz tell me how i can prepare for….what is the future of polymer science.

  14. Mukesh Kumar

    Dear All,
    I am a B.Tech.Paint Technology from H.B.T.I.Kanpur having around 6 years industrial experience.I am interested for M.TECH.POLYMER SCIENCE.So,plz suggest me it will be better for me or not.
