The trouble with polymers produced with a radical-mechanism (see above) is there was usually a large degree of branching. This occures during propagation when the chain curls back on itself and then breaks - leaving chains coming out from the main carbon backbone. This made the polymers less dense meaning a relatively low tensile strength.
