以叔碳酸乙烯酯(VeoVa)为醋酸乙烯酯的共聚单体,聚乙烯醇为保护胶体,过硫酸铵(APS)为引发剂,当用SDS和OP-10为复合乳化剂,单体配比VeoVa︰VAc为2︰8,引发剂量为0.7%时,合成出的叔醋乳液吸水率最小;当用反应型乳化剂DNS-86,用量为3 g时,其他配比不变,合成出的叔醋乳液吸水率最小。
以叔碳痠乙烯酯(VeoVa)為醋痠乙烯酯的共聚單體,聚乙烯醇為保護膠體,過硫痠銨(APS)為引髮劑,噹用SDS和OP-10為複閤乳化劑,單體配比VeoVa︰VAc為2︰8,引髮劑量為0.7%時,閤成齣的叔醋乳液吸水率最小;噹用反應型乳化劑DNS-86,用量為3 g時,其他配比不變,閤成齣的叔醋乳液吸水率最小。
이숙탄산을희지(VeoVa)위작산을희지적공취단체,취을희순위보호효체,과류산안(APS)위인발제,당용SDS화OP-10위복합유화제,단체배비VeoVa︰VAc위2︰8,인발제량위0.7%시,합성출적숙작유액흡수솔최소;당용반응형유화제DNS-86,용량위3 g시,기타배비불변,합성출적숙작유액흡수솔최소。
With vinyl ester of versatic acid (VeoVa) as a copolymer of vinyl acetate monomer, polyvinyl alcohol as the protective colloid, ammonium persulfate as initiator, using SDS and OP-10 as composite emulsifier, under the condition of monomer ratio VeoVa: VAc =2:8 and initiator dose of 0.7%, VV emulsion with the lowest water absorption rate was synthesized; when the amount of reactive emulsifier DNS-86 was 3g, other conditions were constant, synthesized VV emulsion had the lowest water absorption.
