Give one reason why polyester is biodegradable
Can hydrolysed
Can react with nucleophililes due to polar bonds
Explain why polyamides can be made into fibres and polyalkenes are usually too weak for this purpose

Which are stronger than /strongest IMF
compared to polyalkenes which only have VDW forces between molecules
