1.	Which of the following types of molecular structure present in thermosetting polymers?(a) Linear polymers(b) Branched polymers(c) Cross-linked polymers(d) Network polymersThe question was posed to me during an interview.I need to ask this question from Processing of Thermosetting Plastics in portion Moulding with Polymers of Casting-Forming-Welding II
Answer» The correct OPTION is (c) Cross-linked POLYMERS Best explanation: Cross-linked polymers are described by ADJACENT linear CHAINS that are brought one to ANOTHER at several locations by covalent bonds. Cross linking is completed by a non-reversible chemical reaction. Often, cross-linking is finished by additive atoms which are covalently bonded to the chains in the thermosetting polymers.
