The role of multifunctional acrylates in radiation grafting and curing reactions

摘要: Abstract Multifunctional acrylates (MFAs) are used extensively in radiation rapid cure (RRC) formulations involving u.v. and EB processing to achieve fast rates of polymerization cross-linking if required. For certain RRC applications, the ability concurrent grafting with can lead improved properties finished product. In current work effect MFAs on during curing process is evaluated from a basic study role these typical reaction initiated by or ionizing radiation. The model for was copolymerization styren polyolefins cellulose. It found that presence MFA related polyfunctional monomers (PFMs) additive amounts styrene solution enhances yield under conditions. Synergistic effects PFMs other additives such as mineral acids, inorganic salts (e.g. lithium perchlorate) specific organic compounds urea) were observed reactions. When silanes fluorinated alkyl esters, which important slip flow cured film, incorporated into monomer solution, former retards whereas latter it. inclusion solutions leads large increases graft both esters. result implies MFAs, addition speeding processes, may also enhance adhesion substrates because an increase concurent cure. A mechanism proposed.
