4.Useage

1.Polymerization:
It can be polymerized to give polyvinylacetate. With other monomers can be used to prepare copolymerssuch as ethylene-vinyl acetate (EVA), vinylacetate-acrylic acid (VA/AA), polyvinyl chloride acetate (PVCA), and polyvinylpyrrolidone (Vp/Va Copolymer, used in hair gels).Due to the instability of the radical, attempts to control the polymerizationvia most 'living/controlled' radical processes have proved problematic.However, RAFT (or more specifically MADIX)polymerization offers a convenient method of controlling the synthesis of PVAby the addition of a xanthate or a dithiocarbamate chain transfer agent.

2.Other reactions:
Vinyl acetate undergoes many of the reactions anticipated for an alkeneand an ester.Bromineadds to give the dibromide. Hydrogen halides add to give 1-haloethyl acetates,which cannot be generated by other methods because of the non-availability ofthe corresponding halo-alcohols. Acetic acid adds in the presence of palladiumcatalysts to give ethylidene diacetate, CH3CH(OAc)2. Itundergoes transesterification with a variety of carboxylicacids.The alkene also undergoes Diels-Alderand 2+2 cycloadditions.

3.Toxicity evaluation:
On January 31, 2009, the Government of Canada's final assessment concludedthat exposure to vinyl acetate is not considered to be harmful to human health.Thisdecision under the Canadian Environmental Protection Act (CEPA) was based onnew information received during the public comment period, as well as morerecent information from the risk assessment conducted by the European Union.


5.Company profile

Qingdao Hisea Chem Co., Ltd is a famous chemical manufacture since 1996, located in Chemical Logistics Park of Qingdao port which is only 30 kilometers from the Qingdao port, and the traffic is very convenient.
