Oxirane, methyl-, polymer with oxirane, ether with 1,2,3-propanetriol grafted with styrene, acrylonitrile and 1,1-dichloroethylene, CAS # 124199-65-1
The vinyl polymer is in dispersed form, therefore the viscosity increase due to grafting is not proportional to MW, but is related to particle size and crowding of particles..
