Haryana polytechnic syllabus trade CHEMICAL ENGG Spl. Paint Tech 3rdsem Polymer Sci

Haryana polytechnic syllabus trade CHEMICAL ENGINEERING (Spl. Paint Tech) 3rd semester / subject POLYMER SCIENCE for the session 2012-13 and you can read the syllabus as well as download from here.

RATIONALE
The subject is designed to enable the students to acquire basic knowledge of polymers, their advantages, application, classification and conversion. This will help the students in identifying different polymeric materials to be processed in the industry and determine their quality based on physical and chemical properties.
