1. The initial setting reaction is photochemical polymerisation.

2. A number of chemists had experimented with the polymerisation of ethylene using catalysts.

3. Keep away from acids, reducing agents and polymerisation catalysts.

4. Also known as chain-growth polymerisation.

5. Large molecules resulting from the simultaneous polymerisation of two or more monomer units.

6. The invention also relates to a polymerisation device for producing polylactide and to a method for recycling process steam produced during the production of polylactide.

7. The effect of solvent, catalyst, and polymerisation conditions on the formation of I was studied.

8. For most polymers. made by addition polymerisation, this is done by heating the polymer above its ceiling temperature in the absence of oxygen.

9. The polymerisation of the monomer is carried out by UV curing the mixture when it was kept in a specific phase which can be obtained by controlling the temperature of the ferroelectric liquid crystal.

10. The extra-oral treatment requires processing at temperatures closer to the glass transition temperature where segmental mobility allows additional polymerisation.

11. Above a certain temperature, monomers can no longer be persuaded to form polymers by chain polymerisation.

12. Stable under ordinary conditions of use and storage. Discolours on exposure to light. Hazardous polymerisation will not occur.

13. Synthetic aliphatic polyesters are synthesised from diols and dicarboxylic acids via condensation polymerisation, and are known to be completely biodegradable in soil and water.

14. A compound required to start a chain reaction, such as free - radical polymerisation.

15. The relations of the different characteristics of maltodextrin with dextrose equivalent and degree of polymerisation are also reviewed.

16. The brightening polyester chip is made by addition of brightening agent during the polymerisation.

17. The invention also envisages a method for the preparation of a coloured polymer, the method comprising performing a polymerisation reaction in the presence of such a catalyst.

18. Explain why the extraction of casein from milk is not a polymerisation reaction.

18. try its best to gather and build good sentences.

19. According to the invention, the droplets contain at least one monomer and are coated with particulate solids during the polymerisation process.

20. Different maltodextrins are distinguished by two indexes which are dextrose equivalent and degree of polymerisation.

21. Application: Mainly be used for pharma material , agriculture chemicals and organic synthesis. As Ziegler-Natta-type olefin polymerisation catalyst in PP and PE polymerisation.

22. This advance has been made possible through a patented polymerisation breakthrough technology.

23. The third approach involves: 1) the synthesis of certain molecules containing readily polarised groups of substituents, and 2) the controlled polymerisation or crystallisation of these molecules.

24. Other polymers, such as those made by step growth polymerisation may be more easily depolymerised. by undoing the condensation or elimination reaction that caused the monomer units to join.
