7 Plastics are polymers. They are formed from their monomers by polymerisation.(a) Two methods for the disposal of waste plastics are.burning recycling.Describe one advantage and one disadvantage of each method.buming recycling[4](b)(i) There are two types of polymerisation reaction. Give their...
On the other hand, the use of agricultural biopolymers that are easily biodegradable not only would solve these problems but would also provide a potential new use for surplus farm production. Unfortunately, films from agricultural polymers are initially inferior to synthetic polymers mostly because of...

aBiodegradable Polymers: For the polymerization of heterocyclic monomers such as L-lactide, electrophilic Lewis acids are required to initiate the ring-opening process. In the context of developing new biocompatible and bioresorbable polymers for potentially biomedical applications, we have focused on the...
of polymers that is independent of their origin and can be altered after tuning at the molecular level. Therefore, some polymers are produced from petroleum feedstocks but are biodegradable. Therefore, in addition to naturally derived biopolymers, there are also petroleum-based biodegradable biopolymers...

- The process of combining monomers to form polymers is called polymerization. This can occur through various mechanisms, such as addition polymerization and condensation polymerization. 4.Types of Polymers: - There are different types of polymers based on the nature of their monomers: ...
Abstract Aim The pollution caused by agricultural plastic mulch film and the resulting microplastics has garnered significant attention. The partial application of biodegradable plastic mulch film (BPM) appears to be a promising method for reducing plastic pollution in agricultural soil. ...
In addition, nanotechnology has greatly revolutionized the healthcare sector, with its utilization extending to biomedical and dental treatment. Currently, it is being applied in multiple areas of diagnosing, preventing, and treating oral disorders [7]. The field of dentistry has incorporated the use...
