Synthesis of Diacetone Acrylamide Study on preparation and properties of the aqueous latex with DAAM

含双丙酮丙烯酰胺（DAAM）的水性乳液的制备与性能研究

The acrylic polymer emulsion incorporated with keto groups was prepared by conventional method using DAAM ( diacetone-acrylamide ) as a functional monomer .

以双丙酮丙烯酰胺作为官能单体，与其它乙烯基单体共聚合成了含有酮羰基的聚丙烯酸酯乳液。

When the content of DAAM was 33.64 % , the intrinsic viscosity was increased by 9.9 times , and the copolymer has good salt-resistant property .

通过对各种组成共聚物在不同盐溶液中的特性粘数的测定表明，该共聚物具有良好的耐盐性能。

In this paper , we synthesize a vinyl monomer-Diacetone Acrylamide ( DAAM ) which can introduce keto group into the acrylic polymer .

本文合成了一种含有酮羰基的乙烯基单体&双丙酮丙烯酰胺（DAAM）。

Adoption of this crosslinking mode could markedly improve water resistance , solvent resistance , glossiness and hardness of the film . 6.5w % DAAM out of total monomer mass was preferred .

采用该交联体系，可显著提高涂膜的耐水性、耐溶剂性、光泽度及硬度，DAAM的用量以占总单体质量的6.5%为好。

Studies were made of preparation of acrylic latex coating crosslinked at ambient temperature with diacetone acrylamide ( DAAM ) as crosslinking monomer and adipic dihydrazide as curing agent .

对以双丙酮丙烯酰胺（DAAM）为交联单体，己二酰肼为固化剂制备室温交联丙烯酸乳胶漆进行了研究。

Diacetone acrylamide ( DAAM ), which is usually called diamine for short and has non-toxicity , can copolymerized with other compounds , degrade into intermediate product and can function as an extremely good bio-material .

双丙酮丙烯酰胺（DAAM）常被简称为双胺，极易与其它物质发生聚合反应，双丙酮丙烯酰胺本身无毒，能分解成生物中间体，是一种极好的生物材料。

Ambient self-crosslinking latex comprised of DAAM and acrylamide was also prepared and when the dosage of DAAM was beyond 2 % , the hardness of film reached 2H , but latex without other groups had bad water resistance and was unsuitable in practice .

同时合成了含DAAM（双丙酮丙烯酰胺）、丙烯酰胺的室温自交联乳液，在DAAM含量2%以上涂膜的硬度就达到了2H，但是不含其它官能团的这种乳液，耐水性较差，不适合于实际应用。
