Detailed Analysis

CourseMarks Score®

9.0 / 10

CourseMarks Score® helps students to find the best classes. We aggregate 18 factors, including freshness, student feedback and content diversity.

Freshness Score

10.0 / 10
This course was last updated on 5/2022.

Course content can become outdated quite quickly. After analysing 71,530 courses, we found that the highest rated courses are updated every year. If a course has not been updated for more than 2 years, you should carefully evaluate the course before enrolling.

Student Feedback

We analyzed factors such as the rating (0.0/5) and the ratio between the number of reviews and the number of students, which is a great signal of student commitment.

New courses are hard to evaluate because there are no or just a few student ratings, but Student Feedback Score helps you find great courses even with fewer reviews.

Content Score

7.5 / 10
Video Score: 7.8 / 10
The course includes 1h 49m video content. Courses with more videos usually have a higher average rating. We have found that the sweet spot is 16 hours of video, which is long enough to teach a topic comprehensively, but not overwhelming. Courses over 16 hours of video gets the maximum score.
Detail Score: 9.2 / 10

The top online course contains a detailed description of the course, what you will learn and also a detailed description about the instructor.

Extra Content Score: 5.5 / 10

Description

Natural polymers: The polymers which occur in nature i.e., which occur
either in plants or animals, are called natural polymers. For example,
natural rubber, proteins, cellulose, starch (polysaccharides), wood, silk and
nucleic acids are natural polymers.
Synthetic polymers: Synthetic polymers are man-made polymers. These
polymers are made in laboratories or factories. Typical examples of
synthetic polymers include polyethene, PVC, nylon, terylene, Teflon,
synthetic rubber, Bakelite and melamine.
Semi-synthetic polymers: Chemically modified natural polymers are
called semi-synthetic polymers. For example, nitrocellulose, cellulose
acetate etc. are termed semi-synthetic polymers. These polymers are also
called chemically modified natural polymers.
Linear chain polymers: The polymers m which the constituent monomers
link with each other to form a long straight chain are called linear chain
polymers, or straight chain polymers.
Linear polymers are well packed and thus have high densities, high tensile
strength and high melting points. For example, high-density polythene
(HDPE) is a linear chain polymer.
Branched chain polymers: The Polymers which have side-chains
attached to the linear chains consisting of monomers are called branched
chain polymers.
The branched chain polymers are irregularly packed and thus have lower
tensile strength, lower melting point and lower density. For example,
low-density polythene (LDPE) has lower density, lower melting point and
lower tensile strength than the linear high-density polythene (HDPE).
