Why DryAdd?

For polymer chemists who want to understand the effects of changing monomer composition and reaction rates on polymer architecture, DryAdd provides a new dimension to lab work and polymer characterization. Find out more about how DryAdd relates to specific characterization techniques here.

DryAdd models polymerization, by setting up a 'virtual reaction pot' which simulates a real system - for example a coating, adhesive, polyurethane, or polyester... DryAdd's new wizard-driven interface guides you step by step through setting up a new simulation.

Whether the system is cross-linked or not, DryAdd provides key insights to drive new product design, and to supplement your characterization studies.

DryAdd has been used by major multinationals to model the polymerization, crosslinking and cure processes in condensation polymerizations such as: polyurethanes, epoxies, phenolics, polyesters, siloxanes and urea and melamine formaldehydes

What does DryAdd tell you?

DryAdd gives information on the molecular structure as the polymer chains and any crosslinked network build up. The analysis capabilities of DryAdd let you get at information on detailed chemical architecture which is difficult, and very expensive, to obtain in any other way.

A large range of reaction types can be used in DryAdd-Pro+ including bond formation, bond formation with creation of 1 product site, and bond creation with 2 product sites. (These sites can go on to react subsequently, if appropriate.) Transesterification, reversible and first order reactions are also included, to enable most chemistries to be modeled. DryAdd-Pro+ also allows you to remove molecules from the reaction pot, to force the system from equilibrium. Consequently, DryAdd-Pro+ is ideal for polyester systems.

Analysis capabilities include:

Sequence Analysis
- to look for specific occurrences of monomer sequences - for example, in order to predict phase separation in polyurethanes
Block Sequence Analysis
- to look at the frequency of occurrence of blocks of various lengths, in linear polymers only.
Network Analysis
- a full graph-theoretic treatment which gives you information on the degree of crosslinking, crosslink density, average functionality of branch points - information which relates directly to mechanical properties, including modulus and Tg
System Analysis
- to report on branching in the whole reaction pot. This complements the Network Analysis.
Formula Analysis
- to determine how much of a material has specific chemical functionalities
Fragment Analysis
- to look at the architecture of the polymer fragments in detail
MALDI Analysis
- to assist with analysis of MALDI spectra
