常温下为白色粉状或片状结晶，可溶于水、甲醛、乙醇、丙酮、四氢呋喃、醋酸乙酯、丙烯腈、苯乙烯等有机溶剂，极易与多种单体共聚，形成聚合物，达到较强的吸水性，但本品不溶于正乙烷、石油醚。

At room temperature, it is white powdery or flaky crystal, soluble in water and organic solvents such as formaldehyde, ethanol, acetone, tetrahydrofuran, ethyl acetate, acrylonitrile, styrene,etc. The product is extremely easy to form polymer by copolymerization with various monomer and achieve strong water absorption, but it is insoluble in ethane, petroleum ether.

DAAM具有两种反应性基团，N-取代的酰胺和甲酮，极易于其它乙烯及(是“基”吧？)单体共聚，从而向聚合物中引入酮羰基的化学性质可以使聚合物发生交联接枝等反应，用于制备各种粘合剂、增稠剂、纸张补强剂、交联剂等。

已广泛用于涂料、粘合剂、日用化工、环氧树脂固化剂、感光树脂助剂、纺织助剂、医疗卫生等领域中。

DAAM owns two reactive groups, namely N - substituted amides and ketone. It is extremely easy for copolymerization with other vinyl monomer, thus the introduction of ketone carbonyl chemical properties can lead polymer to crosslinking and graft reaction, which can prepare various adhesives, thickener, paper reinforcing agent, crosslinking agent, etc.

It has been widely used in fields like coatings, adhesives, daily chemical industry, the epoxy resin curing agent, photosensitive resin additives, textile auxiliaries, health care, ect.

应用Application：

头发处理剂 Hair care agent

DAAM的重要特性是其均聚物或共聚物不溶于水，但具有“水呼吸性”，吸水率达自重的20%~30%，当环境湿度小于60%，还能放出水分，利用这 一特点主要能生产喷发胶。        One important characteristic of DAAM is that its homopolymer or copolymer are insoluble in water, but their water absorption rate can reach 20% ~ 30% of its weight. When the environment humidity is less than 60%, they can even release the moisture, then the hair spray can be produced by means of such characteristic.

感光树脂Photosensitive resin

用光亮的、坚硬耐酸碱的固体双胺均聚物生产感光树脂，能使树脂感光速度快，曝光后非影响部分容易去除，从而获得清晰且强度好、耐水性好的版面。

DAAM的另一重要用途是可部分取代明胶，明胶用于感光乳剂，一直以来很难找到理想产品来替代。高纯度的照相用明胶长期以来供不应求，预计感光材料年需明胶量2500吨，但目前国内照相用明胶产量仅数百吨。

Photosensitive resin produced by light, hard, acid and alkali- resistant solid diamine homopolymer   has high resin photographic speed. The non-affected part is easy to be removed after exposure, thus getting a clear paper layout with good strength and resistance to water.

Another important application of DAAM is that it can partly replace gelatin, which is used for photographic emulsions and difficult to be replaced by other ideal products. Gelatin has long been in short supply for high purity of photographic, 2500 tons of gelatin are expected for photosensitive materials, while domestic photographic gelatin production is only hundreds of tons at present.

用于制备塑性凸版印刷版 Used for the preparation of plastic letterpress print

在粘合剂上的运用 Used for adhesives

可用作纤维质化合物、水泥、玻璃、铝及聚氯乙烯的粘结促进剂和改良剂，同时也可压制成压敏粘合剂，又可作为纸张、纺织品及含丙烯基聚合物塑料薄膜的 热敏粘合剂。   Can be used as adhesive promoter and improver for fiber compounds, cement, glass, aluminium and PVC, meanwhile it can also be compressed to produce pressure-sensitive adhesives, and can be used as heat-sensitive adhesives for paper, textiles and plastic film with allyl polymer.

在其他方面的应用The application in other aspects

可作为环氧树脂、船底防锈漆、船底水下涂料、丙烯酸树脂涂料、不饱和聚酯等涂料的固化剂；can be used as curing agent for epoxy resin, anticorrosive paint of ship bottom,  underwater paint of ship bottom, acrylic resin coatings, unsaturated polyester paint, etc;

DAAM的水溶性共聚物单体被有效的应用于具有悬浮固体的澄清；The water-soluble copolymer monomer of DAAM was effectively applied to the clarification of suspended solid;

可用作热制作的激光记录材料；Can be used as the laser recording materials produced by heat;

用作玻璃防模糊剂；Used as glass fuzzy remover;

用作水溶性光敏树脂成分；Used as composition of water-soluble photosensitive resin;

用于水溶性涂料中。Used for water-soluble paints.
