Worked Solution & Example Answer:A portion of a resin made from acrylic acid (CH₂=CHCOOH) is shown - HSC - SSCE Chemistry - Question 9 - 2013 - Paper 1
Step 1
Identify the structure and components
Answer
The provided structure depicts a section of a polymer made from acrylic acid. Each repeating unit contains a carboxylic acid group (–COOH) attached to vinyl groups (–CH₂–CH=). The repeating unit can be generalized as (C₄H₆O₂) resulting from the polymerization of acrylic acid.
Step 2
Describe the properties of the resin
Answer
Resins derived from acrylic acid are known for their clarity, UV resistance, and durability. They have good adhesion properties making them suitable for various applications including coatings and adhesives. Additionally, they exhibit flexibility and chemical resistance.
