Applications

Application：

CYD-6100 CasesCYD-2136PE CasesCYD-701C/D Cases

CYD product is dendritic structure. Dendritic polymers as "the fourth class of new polymer materials", are attractive to the scientific world and industrial circles. The novelty of these materials includes highly branched molecular structure, a large number of surface functional groups, void space in molecules, monodisperse molecular weight distribution and nanoscale dimensions. The structural characteristics of dendritic polymers lead to unique properties such as excellent solubility and dispersion properties, low melt viscosity and solution viscosity

Dispersing Impact Modifier

 

The difference between dendritic polymers and conventional linear polymers.

The newest fourth class of polymer materials

Conventional polymer materials

Structure

1The dendritic molecule is a highly branched structure

2Dendritic polymers have good geometric symmetry structures and large number of surface groups

1The conventional polymer material is a linear or low degree of branching structure

Performance comparisons

1Highly branched structure property of dendrimers makes its high solubility characteristic and ease of processing and application

2Highly branched and roughly spherical structures of dendritic polymers lead to less chain entanglement between molecules and have low melt viscosity

3The highly branched nature of dendrimers reduces regular array of molecular chains,so dendrimers have low glass transition temperature ,are easy to form film and crystallization performance significantly decreased, such as hyperbranched polyesters can be used in the field with high requirements for transparency

4A large number of surface functional groups of dendrimers lead to its high chemical activity and through modifying the end groups, dendrimers can get more functional groups

1The traditional materials can not dissolve in many solvents and that limits the applications

2 The traditional materials generally have a relatively high melt viscosity and are not conducive to processing and application

3The traditional polymers are easy to form crystallization due to linear molecular chain structures, such as polyester
