COMPARISON WITH HEAT CURED ACRYLIC RESIN - It is activated by dimethyl-p-toluidene and hence called cold curing, autopolymerizing or chemically activated materials. - The porosity of self cured materials is greater which may … WebJan 22, 2024. Jim Clark. Truro School in Cornwall. This page looks at the polymerisation of alkenes to produce polymers like poly (ethene) (usually known as polythene, and sometimes as polyethylene), poly (propene) (old name: polypropylene), PVC and PTFE. It also looks briefly at how the structure of the polymers affects their properties and uses.

WebFor example, the copolymer poly (ethylene co vinyl chloride) is created by polymerising an ethylene and vinyl chloride. In Tariff classification, the term 'copolymer' covers all polymers in which no single monomer contributes 95% or more by weight to the total polymer content. WebPolyolefins are a family of thermoplastics that include polyethylene and polypropylene. They are produced by polymerising respectively ethylene and propylene, mainly obtained from oil and natural gas but can also be derived from renewable resources (e.g., sugar cane). Their versatility has made them the most largely used type of plastics ...
