Description

Известны способы вулканизации хлорсульфированного полиэтилена (ХСПЭ) первичными алифатическими и ароматическими полиаминами .Known methods of vulcanization of chlorosulfonated polyethylene (HSPE) primary aliphatic and aromatic polyamines.

Продукты, используемые в известном способе , высоко токсичны, высоко летучи, кроме того происходит преждевременна  вулканизаци  смесей.The products used in the known method are highly toxic, highly volatile, and premature vulcanization of the mixtures occurs.

С целью повышени  химической стойкости вулканизатов и стойкости к тепловому старению в качестве нового вулканизующего агента дл  ХСПЭ предлагаетс  примен ть &,« бисамипо- (полидифенилсилоксиарилены).In order to improve the chemical resistance of vulcanizates and the resistance to heat aging, it is proposed to use & Bisimipo (polydiphenylsiloxyarylenes) as a curing agent for CSPA.

Пример 1. 100 мл 18%-ного раствора ХСПЭ в толуоле смешивают с 15 мл 15%-ного раствора 1,4-бис- (дифениламиносилокси) -бензола в метилэтилкетоне. Дл  получени  вулканизата смесь выливают в форму. Через 8-12 час образовавшуюс  в форме пленку нагревают в течение 10-120 мин при температуре 150°С. Кинетика -структурировани  ХСПЭ 1,4-бис- (дифениламипосилокси) -бензолом и показатели физико - механических свойств вулканизатов представлены ниже.Example 1. 100 ml of a 18% solution of CSPA in toluene is mixed with 15 ml of a 15% solution of 1,4-bis (diphenylaminosyloxy) benzene in methyl ethyl ketone. To obtain the vulcanizate, the mixture is poured into a mold. After 8-12 hours, the film formed in the form is heated for 10-120 minutes at a temperature of 150 ° C. The kinetics of HSPE-structuring with 1,4-bis- (diphenylamposiloxy) -benzene and the indicators of the physicomechanical properties of vulcanizates are presented below.

Пример 2. К ХСПЭ добавл ют на вальцах 1,4-бис-(дифениламиносилокси) -бензол. Полученные смеси вулканизуют в течение 60 мин при температуре 155°С, смеси 2 и 9EXAMPLE 2 1,4-bis (diphenylaminosyloxy) benzene was added to CSPA on a roll mill. The resulting mixture is vulcanized for 60 minutes at a temperature of 155 ° C, a mixture of 2 and 9
